1 Product definition1.1 Product catalogue

Product name: Dimming actuator, 1-gang / Dimming actuator, 2-gang / Dimming actuator,4-gang

Use: Actuator

Design: Rail-mounted device

Order No. 2171 00 / 2172 00 / 2174 00

1.2 FunctionThe universal dimmer actuator works according to the phase cut-on or phase cut-off dimmingprinciple and makes switching and dimming of HV incandescent lamps, HV halogen lamps andLV halogen lamps with inductive transformers or Tronic-Transformers possible by means ofconventional transformers and Tronic-Transformers. When using the application program withthe version "1.2" in conjunction with devices of the generation "V02", it is also possible toactivate dimmable HV-LEDs or compact fluorescent lamps.The characteristic of the connected load - provided that the load is supported - can beautomatically measured separately for each output channel and the appropriate dimmingprocedure can be set. Alternatively, it is possible to predefine the dimming procedure using theETS configuration. This procedure is necessary for loads that do not enable automaticcalibration (e.g. with HV-LED lamps or compact fluorescent lamps).There are up to 4 dimming channels available depending on the device variants. To simplify theconfiguration, all existing dimming channels can be assigned to the same parameters in theETS and thus configured identically. The number of parameters is thereby reduced in the ETSand applied automatically on all channels.To increase the channel power, the device variant "4-gang" can be wired in parallel by reducingthe number of channel outputs (not with HV-LED lamps or compact fluorescent lamps). Theassignment of parallel to wired dimming outputs to the KNX-controllable dimming channelstakes place in the ETS.The device permits the separate feedback of the individual switching and brightness statuses ofthe connected loads to the KNX. Moreover, a short-circuit and load failure can be signalledseparately to the KNX for each dimming channel.The operating elements (4 pushbuttons) on the front panel of the device allow the dimmingchannels to be switched on or dimmed by manual operation in parallel with the KNX evenwithout bus voltage or in a non-programmed state. This feature permits fast checking ofconnected loads for proper functioning.For project design and commissioning of this device, we recommend using the ETS3.0 fromversion "d" patch "A" , ETS4.1 or earlier. The advantages with regard to downloading (shorterloading times) are available only if this ETS versions are used. Using the ETS4 can result inadditional benefits in terms of parametric representation.The function features that are independently adjustable for every dimming channel by means ofthe ETS include, for example, separately configurable brightness ranges, extended feedbackfunctions, a disabling function, or alternatively, a forced position function, a logic operationfunction, separately adjustable dimming behaviour, soft dimming functions, time delays and astaircase function with pre-warning before switching off the lighting.Furthermore, each dimming channel can be integrated in up to 8 scenes with various brightnessvalues. Central switching of all channels is possible, too. Moreover, the brightness values of thedimming channels in case of bus voltage failure or bus voltage return and after ETSprogramming, can be preset separately.The switch-on times of the dimming channels can be detected and evaluated separately byoperating hours counters.

Product definition


Apart from controlling lighting, the universal dimmer actuator 1-gang can be used as a speedcontroller of single-phase electric motors. This operating mode can be preselected in the ETSand has an effect on the parameter configuration and function of the device.The device has a mains voltage connection that is independent of the load outputs for supplyingthe device electronics of the manual operation and integrated bus coupling unit. The deviceelectronics and bus coupling unit are also supplied from the bus coupling unit so that an ETSprogramming operation or manual operation is also possible even if the mains voltage is notconnected or is switched off. As long as the bus voltage is connected and ready for operation,the device's internal power supply is switched off to save energy.The load outputs have separate mains voltage connections for supplying the digital dimmerpacks and the connected load.The device is designed for mounting on DIN rails in closed compact boxes or in powerdistributors in fixed installations in dry rooms.

i Different device generations and application program versions are available thus resultingin functional differences - particularly with regard to the activation of HV-LED lamps andcompact fluorescent lamps. It is possible to distinguish between the application programsand device generations by means of the version designation (see page 35).This product documentation describes the scope of functions of all application programsand device generations and will deal with the functional differences at the appropriateplaces if necessary.

2.3 Fitting and electrical connectionDANGER!Electrical shock when live parts are touched.Electrical shocks can be fatal.Before working on the device, disconnect the power supply and cover up liveparts in the working environment.

Fitting the deviceo Fit the device by snapping it onto a DIN rail in acc. with EN 60715. The screw terminals for

the load connection should be at the top.i A KNX data rail is not required.i Observe the temperature range and ensure sufficient cooling, if necessary.i Maintain a distance of 1 module, approx. 18 mm, between the devices when operating

multiple dimmers or power boosters within a sub-division in order to avoid overheating.

Connecting the power supply for the device electronics and loadNote permitted loads.Observe the technical connection conditions of the electric power company.Do not exceed permissible total load including transformer power dissipation.Operate inductive transformers with at least 85% nominal load.For mixed loads with inductive transformers at an output: ohmic load max. 50%.Trouble-free operation is only ensured with electronic transformers manufactured by us or withinductive transformers.

CAUTION!Danger of destruction from mixed loads.The dimmer and load may be destroyed.Do not connect capacitive loads, e.g. electronic transformers, and inductiveloads, e.g. inductive transformers, together on the same dimmer output.Do not connect inductive transformers together with HV LED lamps or compactfluorescent lamps on the same dimmer output.

o Connect the bus, the connection of the power supply and the load according to theconnection diagram.(Figure 4).

o Do not switch on the mains voltage yet! First carry out the commissioning (see page 16).

Page 9 of 157



Figure 4: Electrical connection (using the example of the 4gang display variant)

i The supply of the load outputs and mains voltage of the device (terminals "L") can beconnected to various conductors (L1, L2, L3).

i The N terminals for supplying the load outputs (connection required!) are not bridged in thedevice. Hence, different FI electric circuits can be connected to the device.

i Depending on availability of individual dimming outputs, increased power is possible by theconnection of additional power boosters from our company (not with HV LED or compactfluorescent lamps!). Choose power boosters that are suitable for the dimmer and load! Foradditional information, please always refer to the instructions for the power extensions inquestion.Only with application program version "1.2" and device generation "V02": If the outputpower is increased by means of universal power boosters, the configuration of thecorresponding channel must be adapted in the ETS (see parameter "Operation withuniversal power booster ?").Only with application program version "1.1" and device generation without versiondesignation or "V01": When extending the power of an output by means of universal powerboosters, the maximum brightness (ETS parameter) must be reduced to 90 % at most!

i If HV-LED and compact fluorescent lamps are connected to a dimmer output, a powerextension by power boosters is generally not possible!

i Flickering of the connected lamps due to undershoot of the specified minimum load orthrough centralised pulses from the power stations. This does not represent any defect inthe device.

Page 10 of 157



i If the dimming principle should or cannot be universally calibrated, it must be adapted tothe connected load (ETS parameter). In the as-delivered state, the load type is set to"universal" for all channels.

i Only for program version "1.2" and device generation "V02":When connecting dimmable HV-LED lamps or compact fluorescent lamps, the load typethat is suitable for this purpose must always be configured in the ETS. Before switching onthe mains voltage, commissioning using the ETS is essential in this case (see page 16-17).Only connect lamps of one manufacturer and of the same type on the same output. Do notconnect any other loads.HV-LED and compact fluorescent lamps generate high pulsed currents, when they areoperated in the leading edge phase control. Depending on the design and power rating ofthese lamps, the actual connected load of the specified values (label, housing orpackaging) could vary.

i Only for device generation without version designation (not for "V01" or "V02"):It is not possible to operate the device with universal power boosters in conjunction withelectronic transformers! Please use Tronic power boosters for power extension whenoperating electronic transformers.

i Dimming results and dimming quality could vary depending on cable lengths, gridconditions and other influencing factors. Depending on the design and power rating of thelamps, the connected load of the specified values could vary. We do not assume anyresponsibility for the function, dimming results and dimming quality in connection with HVLED and will not accept any liability.

Wire outputs in parallel (only for device variant "4-gang")To increase the channel power, the device variant "4-gang" can be wired in parallel by reducingthe number of channel outputs. The assignment of parallel to wired dimming outputs to theKNX-controllable dimming channels takes place in the ETS. By combining all 4 dimmingoutputs, the connected load can thereby be increased to a max. of 950 Watt.

CAUTION!Risk of destruction if a wrong channel effect is configured for parallel wiring ofoutputs in the ETS.The dimmer and load may be destroyed.In the case of parallel switched outputs, check the parameter settings andadjust if necessary before switching on the mains voltage.

CAUTION!Danger of destruction. 400 V are shorted when outputs switched in parallel areconnected to different outer conductors.The device will be destroyed.Always connect outputs switched in parallel to the same outer conductor.

o Wire the corresponding outputs in parallel according to connection diagram (Figure 5).o Do not switch on the mains voltage yet! First carry out the commissioning (see page 16).

Page 11 of 157



Figure 5: Electrical connection for parallel wiring of outputs (example)

i The L terminals of the parallel wired outputs must be connected to the same outerconductor!

i Parallel wired outputs can only be utilized up to a max of 95 % each.-> 2 outputs in parallel: Maximum connected load 475 W!-> 3 outputs in parallel: Maximum connected load approx. 710 W!-> 4 outputs in parallel: Maximum connected load 950 W!

i In the case of parallel wiring of dimming outputs, it is not permitted to connect additionalpower extensions to the load outputs concerned!

i Do not connect any HV-LED lamps or compact fluorescent lamps to dimmer outputsswitched in parallel.

i With the "2-gang" device variant the dimming outputs cannot be wired in parallel.

Connecting motors (only for "1-gang" device variant)Apart from controlling lighting, the universal dimmer actuator 1-gang can be used as a speedcontroller of single-phase electric motors. This operating mode can be preselected in the ETSand has a considerable effect on the parameter configuration and function of the device.

Page 12 of 157



CAUTION!Risk of destruction if a wrong operating mode is configured in the ETS whenconnecting motors.The dimmer and motor load may be destroyed.When connecting motors, check the parameter settings and adjust if necessarybefore switching on the mains voltage.

o Connect single-phase electric motors according to connection diagram (Figure 6).o Do not switch on the mains voltage yet! First carry out the commissioning (see page 16).

Figure 6: Electrical connection of single-phase electric motors

i Do not connect any three-phase motors!i When connecting several motors in parallel, observe the maximum output power of the

device! Only connect motors of identical type in parallel!i With the operating mode "speed controller", it is not permitted to connect additional power

extensions to the power output!

Page 13 of 157



i In the as-delivered state of the device, the "lighting control" is preconfigured as operatingmode. When connecting a motor, the "speed controller" operating mode must beconfigured in the ETS.Before switching on the mains voltage, commissioning using the ETS is essential (seechapter 2.4. Commissioning).

Changing connected load typeIf one of the connected loads is changed after the commissioning, another load type can alsoresult due to the load change - for example, when replacing a ceiling luminaire with anincandescent lamp by a low voltage illuminant with a conventional transformer, by HV LED orcompact fluorescent lamps. The load type has an influence on the dimming principle to be used(phase cut-on, phase cut-off, universal). The load type and the resulting dimming principle canbe configured in the ETS.If the load type is set to "universal", the dimmer actuator in this case must be recalibrated to thenew load. To do this, the mains voltage of the load must first be switched off as well.It is always necessary to ensure that the load type configured in the ETS matches theconnected load!

CAUTION!Risk of destruction if the preset dimming principle and connected load do notmatch.The dimmer and load may be destroyed.Before changing the dimming principle, observe load type.Before changing the load type, make sure that the dimming principle is correct.Before changing the load type, disconnect the mains voltage of the device andthe load circuit concerned. Check parameter settings and adjust if necessary.

o Disconnect the mains voltage of the load circuit.In this case, depending on the ETS configuration, a load failure telegram can betransmitted to the bus if necessary (see "Load failure detection").

o Connect changed load.o Put device into operation again (see page 16).i When connecting dimmable HV-LED lamps or compact fluorescent lamps, the load type

that is suitable for this purpose must be configured in the ETS.Operate dimmable HV-LED lamps or compact fluorescent lamps – depending on thespecifications of the lamp manufacturer – preferably in the leading edge phase control. Ifthe dimmer buzzes in this operating mode, check operation in the trailing edge phasecontrol.

i In the function as speed controller (only with device variant "1-gang"), the load type andthus the dimming principle is predefined to unalterable in the ETS configuration (phase cut-on operation).

i If the mains voltage supplies of the load outputs and the actuator are connected to variousconductors, it is recommended to also install a multipolar circuit breaker for completeenabling.

Installing / removing the protective capTo protect the bus lines against hazardous voltages in the area of the connecting terminals, aprotective cap can be installed.The cap is installed with the bus terminal in place and the connected bus line led out at the rear.o To install the cap: slide the cap over the bus connecting terminal until you feel it engage

(Figure 7).

Page 14 of 157



o To remove the cap: Remove the cap by pressing the sides slightly and by pulling it out tothe front (Figure 7).

Page 15 of 157



2.4 CommissioningAfter installation of the device and connection of the bus line and mains voltage as well aselectrical loads, the device can be put into operation. The following procedure is generallyrecommended...

Commissioning with the ETSThe device must be installed completely and connected to the mains voltage and loads.i The device has a mains voltage connection that is independent of the load outputs for

supplying the device electronics of the manual operation and integrated bus coupling unit.The device electronics and bus coupling unit are also supplied from the bus coupling unitso that an ETS programming operation or manual operation is also possible even if themains voltage is not connected or is switched off. As long as the bus voltage is connectedand ready for operation, the device's internal power supply is switched off to save energy.

The mains voltage is switched off completely.Before programming the application program and parameters using the ETS, it must be ensuredthat the channel effect parameter configuration (parallel wiring) and the load type (dimmingprinciple) correspond to the electric loads connected to the actuator.

DANGER!Electrical shock when live parts are touched.Electrical shocks can be fatal.Before working on the device, disconnect the power supply and cover up liveparts in the working environment.


o Switch on the bus voltage Make sure that the bus voltage is available interruption freeduring the commissioning.Check: When the programming button is pressed, the red programming LED must light up.

o Configure and program the physical address with the help of the ETS.o Download the application data with the ETS.o Switch on mains voltage supplies of the load circuits.

The device calibrates itself to the loads and selects the appropriate dimming procedure ifthe load type is set to "universal" in the ETS. The dimming procedure can also bepredefined with the parameterization. In this case, the calibration procedure is notnecessary.Afterwards, the actuator sets the brightness on the outputs that is predefined in the ETS inthe "Behaviour after bus or mains voltage return" parameter. During the calibration phase,operations received are performed after finishing the calibration procedure.

o Switch on mains voltage supply of the dimmer actuator (terminal pair "L N").The device is ready for operation.

i The calibration procedure becomes noticeable during ohmic loads by a brief flicker andlasts between 1 to 10 seconds depending on the network conditions.

Page 16 of 157



i The mains voltages of the load circuits and the mains voltage supply of the actuator areswitched on simultaneously if, for example, all connections are clamped on the same outerconductor via a circuit breaker. If the load outputs and mains voltage of the dimmeractuator are supplied by different outer conductors or several circuit breakers, the loadcircuits should always be switched on before the mains voltage supply of the dimmeractuator. This ensures correct calibration of the actuator even for long conducting paths tothe load.

i If a short-circuit is detected on a load output during the commissioning, the actuator cannotcalibrate to the load. In this case, the fault must first be eliminated and the short-circuitreset (see page 24-25).

i When the mains supply is on, the outputs of the actuator can be switched manually even ifthere is no bus voltage or if the actuator is not yet programmed. Due to this feature, theloads connected to the individual outputs can be checked for proper functioning alreadyduring site operation.

Setting minimum speed (only for "1-gang" device variant in the "speed controller"operating mode)When deployed as a speed controller, the device must be adapted to the minimum speed of theconnected motor.The ETS commissioning was performed successfully beforehand (see page 16-17).The device is configured as a "speed controller".

CAUTION!Connected motors must not stop.Risk of destruction for motor and controlling device.Set the minimum speed in such a way that the motor does not stop at aminimum setting.

i The speed of a connected motor (e.g. minimum speed) is configured in the ETS as apercentage value. This value represents the dimming value in percent and is a gauge forthe output signal's phase angle of the actuator (phase cut-on operation).

o Load the connected motor with the maximum load that occurs during operation.o Switch on device by manual or bus control.

The device switches on the connected motor to the cutting-in speed.After the set resting time has elapsed, the device sets the currently required speed.

i In the presetting of the device, the cutting-in speed corresponds to the maximum speed of100 %.

o Slowly reduce the speed setting by means of a dimming procedure, e.g. by manualoperation locally on the actuator, until the motor has reached its minimum permitted speed.While doing so, take the motor follow-up into account.

o Ascertain the current speed by determining the current dimmer setting. This can be done,e.g., by selecting the current value of the communication object "Speed feedback" with thehelp of the ETS.

i The data format of the speed feedback is 1 byte. The actuator transmits dimensionlessdecimal values 0...255 via this object, which correspond to the percentage value range of0...100 % and thus the dimming range of the actuator. Any selected value between 0...255can be easily converted to the percentage value..."Selected value" divided by "255" multiplied by "100 %"Example: Selected value = 128 -> Calculation: (128 : 255) · 100 % = 50 %. The decimalplaces must be ignored.

Page 17 of 157



o Enter the determined value (in percent) as minimum speed in the parameter settings.Round up the value to the predefined values available in the ETS. The decimal valuesequivalent to the percentage values are displayed in the ETS as a configuration aid.

o Download the application data with the ETS.

2.5 Operation2.5.1 Manual operation on device

Function

All load outputs of the device have electronic manual operation. The button field with 4 functionkeys and 3 status LEDs on the front panel of the device can be used for setting the followingmodes of operation...- Bus control: operation from touch sensors or other bus devices.- Temporary manual control: manual control locally with keypad, automatic return to bus

control.- Permanent manual control: local manual control with keypad.

i The operating modes can also be disabled by parameter settings in the ETS.i When manual control is active, the outputs cannot be controlled via the bus.i Manual control is possible only while the actuator is supplied with power from the mains or

bus. In the event of bus and mains voltage failure, manual operation is terminated.i The manual operation mode always ends in the event of bus voltage return.i In manual mode, bus operation can be disabled via a telegram. Manual control is

terminated on activation of the disabling function.i Further details concerning manual control, especially with respect to the possible

parameter settings and the interaction with other functions of the dimmer actuator can befound in chapter 4, "Software description" of the present documentation.

Controls and indicators for manual control

(8) LED cLED ON indicates permanent manual control.

(9) Button ON/ nBrief press: Output ON / Sustained press: Increase output brightness.

Page 19 of 157



(10) Status LED ON/ nLED ON in manual control indicates a switched-on output (Brightness: 1...100 %).

(11) Button OFF/oBrief press: Output OFF / Sustained press: Reduce output brightness.

(12) Status LED OFF/ oLED ON in manual control indicates a switched-off output (Brightness: 0 %).

(13) Button ALL OFFWhen pressing, all outputs are switched off (only in permanent manual operation).

Priorities for manual control

The device distinguishes between different functions that can have an effect on an outputchannel. In order to prevent conflicting output states, each available function has a certainpriority. The function with the higher priority overrides the one with the lower priority...- 1st priority: manual control (highest priority)- 2nd priority: forced position or disabling function- 3rd priority: direct operation via the bus ("switching" & "dimming" & "brightness" objects,

scenes, central function)

Features of the device variant 4gangTo increase the channel power, the device variant "4-gang" can be wired in parallel by reducingthe number of channel outputs. The assignment of parallel to wired dimming outputs to theKNX-controllable dimming channels takes place in the ETS.With a parallel wiring, it is possible in 3-channel operation, for example, to assign the loadoutputs A1 and A2 to the KNX dimming channel 1. These outputs are then wired in parallel. Inthis example, the outputs A3 and A4 are then assigned to the dimming channels 2 and 3 andwork independently.

The parallel wiring of the outputs has influence on the manual operation. In the examplementioned, the outputs A1 and A2 can only be used simultaneously in manual operationbecause they are assigned to the same KNX dimming channel. The Status LEDs on the frontpanel of the device subsequently flash at the same time during manual operation and alwaysindicate the same switching state. This should be taken into account as a special case withdevice variant "4-gang".

Load failure detectionThe universal dimmer actuator with a lighting control can monitor the electric circuits of its loadoutputs independent of each other. The actuator detects the mains voltage supply failures (> 15s) of an output or the interruption of the electric circuit when a load is switched on or off. Theload failure detection in case of use must be enabled separately in the ETS for a dimmingchannel (cf. chapter 4 "Software description").i No message of a load failure is possible with the device variant "speed controller" operating

mode in the "1-gang" and device variant "4-gang" and "parallel wired outputs" (only inapplication program version "1.1"). No load failure message can be configured in the ETSin this case.

A load failure due to an interruption of the load circuit, – e.g. for checking a lamp – can only bereliably detected when a load that interrupts the circuit completely in the case of a fault isconnected to an output. Therefore, a failed lamp can only be clearly detected if ...- just one incandescent light bulb is connected and is faulty (e.g. broken filament),- just one high-voltage halogen lamp is connected and is faulty.

Other loads or mixed loads do not normally permit the detection of a failed lamp. It is onlypossible to detect a faulty lamp if ...- halogen lamps are connected via conventional or electronic transformers,- an Incandescent lamp is connected as mixed load to a conventional or electronic

transformer,- several Incandescent lamps or HV halogen lamps are connected in parallel.

i If the load failure detection is enabled in the ETS, a message telegram "Load failuredetected – 1" is transmitted from the actuator to the bus approx. 15 ...20 seconds afteridentification of the load failure.

i A mains voltage failure of the output is always detected as load failure if the mains voltagefailure lasts longer than approx. 15 seconds.

i A faulty fuse in the primary circuit of a conventional transformer normally results in a loadfailure not being detected.

i In the event of a load failure, the actuator sets the switching status of the dimming channelconcerned to "OFF" and the status of the brightness value to "0" and transmits thesevalues to the bus if enabled in the ETS.

i The actuator initialises the objects "Signal load failure / overload" of all dimming channelsafter an ETS programming operation and after switching on the bus voltage or the mainspower supply according to the current status. In this case, it should be noted that the"Delay after bus voltage return" configured in the ETS must have elapsed before loadfailure message telegrams are transmitted to the bus.

Eliminate load failureThe dimmer actuator has detected a load failure on an output.o Disconnect the mains voltage of the load circuit concerned.o Ascertain the cause of the load failure and eliminate.o Switch on mains voltage again of the load circuit.

Page 23 of 157



The load failure is reset. After resetting the load failure, the dimming channel concerned isswitched off and can subsequently be switched on or dimmed again as usual.

i After eliminating the load failure and switching on the mains voltage again in the loadcircuit, the load is recalibrated if the load type is set to "universal" in the ETS. Thecalibration procedure becomes noticeable during ohmic loads by briefly flickering twice andlasts up to 10 seconds depending on the network conditions.

i At least 15 seconds after switching on the mains voltage, the actuator transmits a messagetelegram "no load failure – 0" to the bus if the load failure was eliminated. Otherwise, a loadfailure message is transmitted again. No message telegram is transmitted within the "Delayafter bus voltage return".

Mains interruptionThe device detects mains interruptions at the load connections, as they are caused by faults inthe public low-voltage power supply, for example. If a detected mains interruption on an outputonly lasts for up to approx. 2 seconds, the dimmer actuator activates the old brightness value forthe outputs concerned after mains return and shows no further reaction.

If the mains interruption lasts for more than approx. 2 seconds, the dimmer actuator generates areset for the outputs concerned after mains voltage return. At the same time, the dimmeroutputs concerned are reinitialized with the ETS configuration data. The load is also recalibratedif the load type is set to "universal" in the ETS. During the initialization after the mains voltagefailure, the outputs affected by the mains failure are switched off. The actuator thereby alsotransmits switching status and value feedbacks to the bus, if configured in the ETS. Thereafter,the dimming channels can be switched on again as usual. If the mains failure lasts longer than15 s, a load failure, if used, is also signalled to the bus (see "Load failure detection").i In the case of a 'hard mains interruption', which is caused, for example, by disconnection

via a circuit breaker, the detection time of the mains failure on the load connections can lastfor up to 7 seconds (instead of 2 seconds) due to additional debounce delays.

In the case of a bus and mains voltage supply failure of the dimmer actuator (terminal pair "L N"next to the bus connection), the reset is always generated for all outputs after mains voltagereturn. At the same time, the dimmer outputs concerned are reinitialized with the ETSconfiguration data. The loads are also recalibrated if the load types are set to "universal" in theETS. After the initialization, the outputs are set according to the ETS parameter "Behaviour afterbus or mains voltage return".After mains return, no reaction occurs provided that the bus voltage was available interruptionfree.

Short-circuit and over-temperature detectionShort-circuit protection and over-temperature protection are integrated in the device for eachoutput.If the device detects a short-circuit, the load is switched off automatically after 7 seconds inphase cut-off operation (capacitive and ohmic loads) or after 100 milliseconds in phase cut-onoperation (inductive loads). After switching off, the actuator transmits a message telegram"Short-circuit present – 1" to the bus for the dimming channel concerned, if this message isenabled in the ETS. A short-circuit must be reset (see page 25-26).If there is an over-temperature in the device, the load is switched off by the temperature controlof the device. The actuator, 15 seconds after switching off, transmits a message telegram "Loadfailure present – 1" to the bus for the dimming channel concerned if this message is enabled inthe ETS. In this state, the dimming channel concerned can no longer be switched on by manualor bus control. To reset such a fault, it might be necessary to switch off the mains voltage supplyof the load outputs. Over-temperatures in the device either occur as a result of self-heating(electrical overload) or external influences (ambient temperature in the control cabinet is toohigh).

Page 24 of 157



i If an over-temperature switch-off occurs, the installation situation of the device must bechecked. If the over-temperature occurs regularly, measures must be taken (e. g. providecooling, increase distance to surrounding devices, reduce connected load).

i If the over-temperature protection is activated again shortly after resetting, the device's self-protection takes effect permanently (the device is then apparently faulty). As a result, thedevice must be replaced.

i With the device variants "2-gang" and "4-gang, the reaction of the dimming outputsdepends on the load situation after an overload-temperature switch-off. The load defines aholding current during an over-temperature switch-off. A dimmer output remains switchedoff permanently after the over-temperature switch-off if the holding current exceeds adefined threshold. In this case, the over-temperature switch-off must be reset "manually"(see page 26-27). If the holding current does not exceed the threshold, the dimmer outputswitches on again automatically after cooling down. At the same time, the outputsconcerned pass through a reset whereby they are reinitialized with the ETS configurationdata. As a result, the load is also recalibrated if the load type is set to "universal" in theETS. Thereafter, the dimming outputs execute the reaction after mains voltage return.

i With the device variant "1-gang", the dimmer output remains switched off permanently afteran over-temperature switch-off. In this case, the over-temperature switch-off must alwaysbe reset "manually" (see page 26-27). In the case of a device's self-protection that takeseffect continuously, it should be noted that a manual reset of the over-temperature switch-off is not possible. The device must then be replaced.

The device is also protected against electrical overload. Electrical overloads occur when thenominal operation parameters of a dimmer output are exceeded temporarily or continuously.The reaction of a device then depends on how great the electrical overload is and whichambient conditions prevail. If the overload exceeds the defined short-circuit threshold, thedevice switches off the dimming channel concerned after 7 seconds at the latest, depending onthe load type. In this case, the actuator generates a short-circuit message on the bus if thisfeedback is enabled in the ETS.If the electrical overload does not exceed the short-circuit threshold, the device does not heat upcontinuously. Whether and how rapidly this self-heating occurs depends essentially on howgreat the overload is and how much the device is thermally influenced from outside. The heatingup of the device causes the over-temperature switch-off to take effect from a certaintemperature threshold. In this case, the actuator generates a load failure message on the bus ifthis feedback is enabled in the ETS.Consequently, the device protects itself constantly by means of short-circuit or over-temperatureswitch-off even in the case of an electrical overload.i Special case "Parallel wired outputs" with the device variant "4-gang".

An over-temperature switch-off is performed selectively for each output, i.e. each loadoutput has its own protection against thermal overload. During a thermal overload, only afew outputs of the dimming channel concerned may switch off because of differenttemperature conditions in the device.

Reset short-circuitIf the device has detected a short-circuit on an output, this fault must then be eliminated and theoutput reset before the dimming channel concerned can be switched on again.The device has detected a short-circuit for an output.o Disconnect the mains voltage of the load circuit concerned.o Switch off mains voltage supply of the device (terminal pair "L N" next to the bus

connection).o Ascertain the cause of the short-circuit and eliminate.o Switch on mains voltage again of the load circuit.

Page 25 of 157



o Switch on the mains supply of the device again.The short-circuit is reset. The dimming channel can subsequently be switched on ordimmed again as usual.

i After eliminating the short-circuit and switching on the mains voltage, the load isrecalibrated if the load type is set to "universal" in the ETS. The calibration procedurebecomes noticeable during ohmic loads by briefly flickering twice and lasts up to 10seconds depending on the network conditions.

i After switching on the mains voltage, the actuator transmits a message telegram "no short-circuit – 0" to the bus if the short-circuit was eliminated. Otherwise, a short-circuit messageis transmitted again.

i If the output of a dimming channel was switched off due to a short-circuit, the actuator alsotransmits switching status and value feedbacks (lighting "OFF") to the bus, if configured inthe ETS.

i In the event of a short-circuit, the actuator handles parallel wired outputs of the devicevariant "4-gang" identically because the short-circuit occurs at the same time for all loadoutputs assigned to the dimming channel. The short-circuit is then reported to the bus viathe dimming channel concerned.

i The reset of a short-circuit detection and thus the message that was transmitted to the buscan also be performed by switching off the dimming channel concerned. It is possible toswitch off via...- the "switching" object with the switching command "OFF",- the "brightness value" object with the value "0",- a scene recall with the brightness value "0",- a manual operation with the command "OFF".A bus voltage failure with subsequent bus voltage return also triggers a short-circuit reset.The reset of a short-circuit message simply by switching off can be helpful whendetermining whether the short-circuit situation is still present. If switching on the dimmingchannel concerned results in a short-circuit message again, there is still a fault in thesystem.To eliminate a short-circuit, for safety reasons, the mains voltage supply of the load anddimmer actuator must always be disconnected as described in the operational procedure!

i The actuator initialises the objects "Signal short-circuit" of all dimming channels after anETS programming operation and after switching on the bus voltage according to theircurrent status. In this case, it should be noted that the "Delay after bus voltage return"configured in the ETS must have elapsed before short-circuit message telegrams aretransmitted to the bus.

Resetting permanent over-temperature switch offThe device has switched off one or more load outputs permanently because over-temperaturewas detected.o Switch off the mains voltage supply of the device (terminal pair "L N") and the mains

voltage supply of all load outputs.o Let the device cool down for at least 15 minutes.o Switch on the mains voltage supply again of the device and mains voltage supply of all load

outputs.At the same time, the dimmer outputs concerned are reinitialized with the ETSconfiguration data. The load is also recalibrated if the load type is set to "universal" in theETS.

o For testing purposes, switch on the dimming channel, which was affected previously due tothe over-temperature switch-off, by manual or bus operation.The connected load switches on.

Page 26 of 157



i If a dimming channel was switched off due to an over-temperature, the actuator alsotransmits switching status and value feedbacks (lighting "OFF") and a load failure message(delayed by 15 seconds) to the bus, if configured in the ETS.

i After switching on the mains voltage supply, the actuator transmits a message telegram "noload failure – 0" to the bus if the source of the over-temperature was reliably eliminated.Otherwise, the over-temperature may reoccur after a certain period of operation.

i If an over-temperature switch-off occurs, the installation situation of the device must bechecked. If the over-temperature occurs regularly, measures must be taken (e.g. providecooling, increase distance to surrounding devices, reduce connected load).

i If the over-temperature protection is reactivated shortly after resetting, the device's self-protection takes effect permanently (the device is then apparently faulty). As a result, thedevice must be replaced.

i Special case "Parallel wired outputs" with the device variant "4-gang".An over-temperature switch-off is performed selectively for each output, i.e. each loadoutput has its own protection against thermal overload. During a thermal overload, just afew outputs of the dimming channel concerned may switch off at first because of differenttemperature conditions in the device.

Overvoltage detectionThe device can detect overvoltage on a dimming output. Overvoltage occurs, for example, if thedimming principle "Phase cut-off" set in the parameters for LED lamps does not match the load.If overvoltage is detected, the device switches off the dimming output affected. This protects thedevice against destruction. If overvoltage is detected, the load is switched off automatically after7 seconds in phase cut-off operation and after 100 milliseconds in phase cut-on operation.After switching off, the actuator transmits a message telegram "Short-circuit/Overload present –1" - as in the case of a detected short-circuit or overload - to the bus for the dimming channelconcerned, if this message is enabled in the ETS. The resetting of a switched-off output due toovervoltage is possible in the same way as the resetting of a short-circuit message (seepage 25-26).

4.2 Software "Dimming 30201x / 30231x / 30261x"4.2.1 Scope of functions

General:- There are up to 4 dimming channels available depending on the device variants.- To simplify the configuration, all existing dimming channels can be assigned to the same

parameters in the ETS and thus configured identically.- With device variant "4-gang": To increase the channel power, outputs can be wired in

parallel by reducing the number of channel outputs (with device generation "V02": not withHV-LED lamps or compact fluorescent lamps). The assignment of parallel to wired dimmingoutputs to the KNX-controllable dimming channels takes place in the ETS.

- For device variant "1-gang": Apart from controlling lighting, the actuator 1-gang can beused as a speed controller of single-phase electric motors.

- Manual operation of the outputs independently of the bus (also building site operationpossible).

- Central switching function for collective control of all dimming channels.- Delay for actively transmitting feedbacks after bus voltage return.Channel-oriented:- Independent control of up to 4 dimmer outputs. Each dimming channel offers the full scope

of functions without any restrictions. All channel-oriented functions can be parameterizedseparately for each dimming channel. This feature permits independent and multi-functional control.

- It is possible to specify the load type and thus define the dimming principle:1. universal (with automatic calibration procedure)2. Electronic transformer (capacitive / phase cut-off principle)3. conventional transformer (inductive / inverse phase principle)4. LED (phase cut-off) - Only with application program version "1.2" and device generation"V02".5. LED (phase cut-on) - Only with application program version "1.2" and device generation"V02".

- Feedback "switching" and "brightness value" configurable. One active (object transmitting)or passive (object readable) feedback function each is configurable. In the case of anactively transmitting object, the feedback values can be optionally cyclical and transmittedwith a delay after a device reset.The actuator updates the feedback values only after a change or after each update of thecorresponding input objects.

- Setting of the dimmable brightness range is possible ("basic brightness and maximumbrightness" or "minimum brightness and maximum brightness").

- Only with application program version "1.2" and device generation "V02": Automatic settingand scaling of the dimmable brightness range when using Universal power boosters.

- Dimming behaviour (also fading) and dimming characteristics configurable.- Soft switch-on and soft switch-off function.- Only with program version "1.2" und device generation "V02": The response of a dimming

channel in the state "OFF" when receiving a relative dimming command can be configured(switch on and dim up or no reaction).

- In the case of a short-circuit and load failure or overload, message telegrams can betransmitted to the bus (load failure/overload message not with "1-gang" device variant inthe speed controller" operating mode"). Feedback of the connected load type is alsopossible.

- Disabling function, or alternatively, forced position function is configurable for each output.During a disabling function, the flashing of connected luminaires is not possible.

- Timing functions (switch-on delay, switch-off delay, staircase lighting timer) With thestaircase lighting timer the reaction at the end of the switch-on time can be configured (pre-warning function by means of time-controlled reduction of the lighting or activation of thepermanent lighting, e.g. for hallways).

Software "Dimming 30201x / 30231x / 30261x"Scope of functions


- Logic operation function possible (not with enabled staircase function). In the logicoperation function the switching value of an additional object can be linked logically to the"switching" object and the result of the logic operation transmitted to the dimming channeloutput.

- A dimming channel can be integrated in up to 8 light-scenes.- The switch-on times can be detected and evaluated by operating hours counters.- Behaviour in case of bus voltage failure and bus voltage return as well as after ETS

programming presettable.

4.2.2 Notes on software

ETS project design and commissioningFor configuration and commissioning of the device, ETS3.0 from Version "d" Patch "A" onwardsor ETS4 is required. Through use of these ETS version or later versions, advantages are gainedwith regard to the programming process. The necessary product database is offered in the*.VD4 format.

Device generations and using the application programsThere are different application programs available. The use of application programs with thenew version together with a specially designated device generation results in functionaldifferences as compared with the combination of older applications and devices. It is possible todistinguish between the application programs and device generations by means of the versiondesignation (see the following table)...

1-gang Dimming 302611 1.1 without or "V01"



Application programs and device generations

The designation of the device generation is attached on the device label. Depending on thedevice variant (1-gang, 2-gang or 4-gang) the designation is in different positions (Figure 9).

Figure 9: Position of the designation of the device generation

This product documentation describes the scope of functions of all application programs anddevice generations and will deal with the functional differences at the appropriate places ifnecessary.

Application programs and device generations can be combined with each other in any wayrequired. Only by combining the new application programs with version "1.2" are the followingextended functions possible in conjunction with the new device generation (designation "V02")...- Activation of HV LED and compact fluorescent lamps,- ON by relative dimming in status OFF configurable ("Switch dimming up channel on" or

"Dimming up is ignored").- Configuration of Universal power boosters.

Only by combining the old application programs (version "1.") with the new device generation("V02") is the scope of functions of the old application supported (see following table). Theprogramming of the new application version ("1.2") in old devices (without designation or "V01")only executes the old scope of functions as well.

Available functions depending on device generation and application versionD = Device generationA = Application version

Safe-state modeIf the device does not work properly - for instance as a result of errors in the project design orduring commissioning - the execution of the loaded application program can be halted byactivating the safe-state mode. The safe-state mode does not permit controlling the outputs viathe bus and by hand. The actuator remains passive since the application program is not beingexecuted (state-of-execution: terminated). Only the system software is still functional so that theETS diagnosis functions and also programming of the device continue to be possible.

Activating the safe-state modeo Shut off the bus and the mains voltage supply.o Press and hold down the programming button.o Switch on the bus or mains voltage. Release the programming button only after the

programming LED starts flashing slowly.The safe-state mode is activated. With a new brief press of the programming button, theprogramming mode can be switched on and off as usual also in the safe-state mode. Theprogramming LED will nevertheless continue to flash independently of the programmingmode as long as the safe-state mode is active.

i The safe-state mode can be terminated by switching off the supply voltage (bus and mains)or by programming with the ETS.

Unloading the application programThe application program can be unloaded with the ETS. In this case, manual control as part ofthe application program is not available either.

4.2.4 Functional description

4.2.4.1 Description of channel-independent functions

4.2.4.1.1 Channel definitionThere are up to 4 dimming channels available depending on the device variants. To increasethe channel dimmer output power, the "4-gang" device variant in particular can be wired inparallel by reducing the number of channel outputs. The assignment of parallel to wireddimming outputs to the KNX-controllable dimming channels takes place in the ETS.i The configuration of the dimming channels has influence on the use of the 4 dimmer

outputs and thus influence on the load distribution.In the ETS on the parameter page "Channel definition", the number of dimming channels to beused is selected. The fewer channels that are configured, the more dimming outputs can beassigned to a channel. The assignment of the KNX controllable dimming channels to thedimming outputs is described in the assignment table (Figure 10), which is also stored in thedevice.The assignment of dimming channel 1 to the outputs can be configured in 2-channel and3-channel operation. This then gives rise to the effect of the other channels on the outputs inaccordance with the channel assignment table. The "Effect of channel 1" parameter defines theassignment and, irrespective of this, specifies the effect of the other channels.

Figure 10: Channel assignment tableOptions of the channel assignment depending on the number of channels

i Parallel wired outputs can only be utilized up to a max of 95 % each.-> 2 outputs in parallel: Maximum connected load 475 W!-> 3 outputs in parallel: Maximum connected load approx. 710 W!-> 4 outputs in parallel: Maximum connected load 950 W!


i Do not connect any HV-LED lamps or compact fluorescent lamps to dimmer outputsswitched in parallel.

Page 46 of 157

Software "Dimming 30201x / 30231x / 30261x"Functional description


i With the "2-gang" device variant the dimming outputs cannot be wired in parallel.Consequently, the parameters for setting the number of channels and the effect in the ETSdo not exist for these device variants. The same holds true for the device variant "1-gangsince only one dimming channel is available here.

i On the parameter page "Connection help", a summary of the channel assignment andpossible connected load of the individual dimming channels is displayed. The informationon this page can help the electrician to connect the electrical load to the dimming outputsand hence to assign it to the KNX-controllable dimming channels when installing thedevice.

To simplify the configuration, all existing dimming channels can be assigned to the sameparameters in the ETS and thus configured identically. The parameter "Setting of the channelparameters" on the parameter page "Channel definition" specifies whether every dimmingchannel of the device can be configured individually or whether all channels should beconfigured by the same parameters.In the "all channels equal" setting, the number of parameters in the ETS is reduced. The visibleparameters are then used on all channels automatically. Only the communication objects canthen be configured separately for the channels. This setting should be selected, for example, ifall channels behave identically and should only be activated by different group addresses (e.g.in office blocks or in hotel rooms).i In the "all channels equal" setting, the number of dimming channels can only at least be

reduced to the 2-channel operation.i In the device variant "1-gang", the parameter "Setting of the channel parameters" is not

necessary because only one channel must be configured here.

Page 47 of 157



4.2.4.1.2 Manual operation

All outputs of the device have electronic manual operation. The button field with 4 function keysand 3 status LEDs on the front panel of the device can be used for setting the following modesof operation...- Bus control: operation from touch sensors or other bus devices- Temporary manual control: manual control locally with keypad, automatic return to bus

control,- Permanent manual control: local manual control with keypad.

The operation of the function keys, the control of the outputs and the status display aredescribed in detail in chapter "Operation" (see page 19). The parameterisation, statusfeedback, disabling via a bus telegram, and interaction with other functions of the device whenmanual control is activated and deactivated are described in greater detail below.

Manual control is possible while the device is supplied with power from the mains or bus. In thestate as supplied the manual control mode is fully enabled. In this unprogrammed state, alloutputs can be controlled by the manual operation so that fast function checking of theconnected loads (e.g. on the construction site) is possible.

After initial commissioning of the actuator via the ETS, manual control can be enabled ordisabled separately for various states of operation. Manual control can, for instance, bedisabled during bus operation (bus voltage applied). Another option consists in the completedisabling of the manual control only in case of bus voltage failure. Therefore manual control canbe disabled completely, if the bus disable and bus failure disable are active.

Enabling the manual control modeManual control for the different states of operation is enabled or disabled by means of theparameters "Manual control in case of bus voltage failure" and "Manual control during busoperation".o Set the parameter "Manual control in case of bus voltage failure" to "enabled".

Manual control is then basically enabled when the bus voltage is off. This settingcorresponds to the setting of the actuator as delivered.

o Set the parameter "Manual control in case of bus voltage failure" to "disabled".Manual control is completely disabled when the bus voltage is off. In this case, busoperation is not possible either so that the outputs of the actuator can no longer beactivated.

o Set the parameter "Manual control during bus operation" to "enabled".Manual control is then basically enabled when the bus voltage is on. The outputs of theactuator can be activated via the bus or manually. This setting corresponds to the setting ofthe actuator as delivered.

o Set the parameter "Manual control during bus operation" to "disabled".Manual control is completely disabled when the bus voltage is on. In this configuration, theactuator outputs can only be operated via the bus.

i In the case of bus voltage failure, an active manual operation will not be terminated even if"Manual operation in case of bus voltage failure = disabled" is configured. This will bedisabled later, only at the end of manual operation.

Page 48 of 157



i Further parameters and communication objects of the manual control are visible only in theconfiguration "Manual control during bus operation = enabled". For this reason, thedisabling function, the status message and bus control disabling can only be configured inthe above parameter setting.

Presetting the behaviour at the beginning and at the end of manual control.The manual control distinguishes the temporary and permanent manual control. The behaviouris different depending on these modes of operation, especially at the end of manual control. Itshould be noted that the operation via the bus, i.e. control of the outputs by direct operation(switching / dimming / brightness value, scenes, central) or by the disabling or forced positionfunctions is always disabled when the manual control is active. This means that the manualcontrol mode has the highest priority.Behaviour at the beginning of manual control:The behaviour at the beginning of manual control does not differ for temporary and permanentmanual control. During activation of the manual operation, the brightness statuses of thedimming channels remain unchanged.Flashing feature during disabling function: The flashing of a disabling function is interrupted atthe beginning of the manual operation. The brightness adapts itself to the switch-on brightness.The switching status is indicated as "ON".Active forced position functions or disabling functions can be overridden by manual control.These functions are reactivated after deactivation of the manual mode unless they have beencancelled via the bus in the meantime.Behaviour at the end of manual control:The behaviour at the end of manual control is different for temporary and permanent manualcontrol.The temporary manual mode is shut off automatically when the last output has been addressedand when the select key c is pressed once more. During a deactivation of the temporarymanual operation mode, the actuator goes back to 'normal' bus operation and does not changethe brightness or speed states selected by manual operation. If, however, a forced position ordisabling function has been activated via the bus before or during manual operation, theactuator executes these functions of a higher priority again for the dimming channelsconcerned.The permanent manual control mode is shut off, when the select key c is pressed for morethan 5 seconds. Depending on the parameterization of the actuator in the ETS, the outputs willbe set to the state last adjusted in the manual mode or to the state internally tracked (directoperation, forced position, disabling) when the permanent manual mode is switched off. Theparameter "Behaviour at the end of permanent manual control during bus operation" defines thecorresponding reaction.o Set the parameter "Behaviour at the end of permanent manual control during bus

operation" to "no change".All telegrams received during an active permanent manual control mode for directoperation (switching, dimming, brightness value, central, scenes) will be rejected. After theend of the permanent manual operation mode, the current brightness or speed state of allchannels remains unchanged. If, however, a forced position or disabling function has beenactivated via the bus before or during manual operation, the actuator executes thesefunctions of a higher priority again for the channels concerned.

o Set the parameter "Behaviour at the end of permanent manual control during busoperation" to "track outputs".During active permanent manual control all incoming telegrams are tracked internally. Atthe end of manual operation, the channels are adjusted to the last tracked brightness orspeed states. If a forced position or disabling function has been activated via the busbefore or during manual control, the actuator executes these functions of a higher priorityagain for the channels concerned.

i The behaviour at the end of the permanent manual control when the bus voltage is off (e.g.building site operation) is permanently set to "no change".

Page 49 of 157



i The control operations triggered in the manual control mode will be transmitted viafeedback objects to the bus, if enabled and actively transmitting.

i On return of bus voltage or after programming with the ETS an activated manual controlmode will always be terminated. In this case, the parameterized or predefined behaviour atthe end of manual control will not be executed. The actuator executes the parameterizedbehaviour on bus/mains voltage return or after ETS programming instead.

Presetting a manual control disableThe manual control mode can be separately disabled via the bus, even if it is already active. Ifthe disabling function is enabled, then as soon as a disabling telegram is received via thedisabling object of the manual control, the actuator immediately terminates an activated manualcontrol and locks the function keys on the front panel of the device. The telegram polarity of thedisabling object is parameterisable.

The manual control mode during bus operation must be enabled.o Set the parameter "Disabling function manual control ?" on parameter page "Manual

control" to "yes".The disabling function of the manual control mode is enabled and the disabling object isvisible.

o Select the desired telegram polarity in the "Polarity of the manual operation disablingobject" parameter.

i If the polarity is "0 = disabled; 1 = enabled", the disabling function is immediately active onreturn of bus/mains voltage or after an ETS programming operation (object value "0"). Toactivate the manual control in this case, an enable telegram "1" must first be sent to thedisabling object.

i In case of bus voltage failure, disabling via the disabling object is always inactive(depending on parameterization, the manual control is then either enabled or completelydisabled). After return of bus voltage, a disabled state that was active beforehand is alwaysinactive when the polarity of the disabling object is non-inverted.

i When an active manual control is terminated by a disable, the actuator will also transmit a"Manual control inactive" status telegram to the bus, if the status messaging function isenabled.

Presetting the status message function for the manual control modeAn actuator can transmit a status telegram to the bus via a separate object when the manualoperation is activated or deactivated. The status telegram can only be transmitted when the busvoltage is switched on. The polarity of the status telegram can be parameterised.The manual control mode during bus operation must be enabled.o Set the parameter "Status manual control ?" on parameter page "Manual control" to "yes".

The status messaging function of manual control is enabled and the status object is visible.o Specify in the parameter "Status object function and polarity" whether the status telegram is

generally a "1" telegram whenever the manual control mode is activated or only in thosecases where the permanent manual mode is activated.

i The status object is always "0" when the manual control mode is deactivated.i After bus voltage return, the status will only be transmitted actively to the bus ("0") if a

manual control, activated during a bus voltage failure, is ended by the bus return. Thestatus telegram is in this case transmitted without delay.

Page 50 of 157



i When active manual control is terminated by a disable, the actuator will also transmit a"Manual control inactive" status telegram to the bus.

Setting disabling of the bus controlIndividual dimming channels can be disabled locally so that the connected loads can no longerbe controlled via the KNX. Such disabling of the bus operation is initiated by operation inpermanent manual operation and is indicated by rapid flashing of the status LEDs on the frontpanel of the device concerned. The disabled outputs can then only be activated in permanentmanual control.The manual control mode during bus operation must be enabled.o Set the parameter "Bus control of single channels during bus operation can be disabled?"

on parameter page "Manual control" to "yes".The function for disabling the bus control is enabled and can be activated locally. As analternative, this parameter can be set to "no" to prevent activation of disabling of the buscontrol in permanent manual control.

i The disabling initiated locally has the highest priority. Thus all other functions of theactuator that can be activated via the bus (e.g. forced position or disabling function) areoverridden. Depending on the parameterization of the actuator in the ETS, the groups willbe set to the state last adjusted in the manual mode or to the state internally tracked (directoperation, forced position, disabling) when the permanent manual mode is reactivated andsubsequently shut off.

i Any disabling of the bus control activated locally is not reset after bus voltage return if themains voltage was switched on interruption free. A failure of the bus and mains voltage orETS programming operation always deactivates the disabling of the bus control.

Page 51 of 157



4.2.4.1.3 Delay after device resetTo reduce telegram traffic on the bus line after bus voltage activation (bus reset), afterconnection of the device to the bus line or after programming with the ETS, it is possible todelay all actively transmitted feedback telegrams of the actuator. For this purpose, a channel-independent delay can be specified (parameter "Delay after bus voltage return" on parameterpage "General". Only after the configured time elapses are feedback telegrams for initialisationtransmitted to the bus.It is possible to configure separately which of the channel-oriented feedback telegrams areactually delayed for each dimming output or for each feedback function.i The delay has no effect on the behaviour of the individual dimming channel. Only the

feedback telegrams are delayed. The channels can also be activated during the delay afterbus voltage return.

i A setting of "0" for the delay after bus voltage return deactivates the delaying functionaltogether. In this case, all feedback telegrams, if actively transmitted, will be transmitted tothe bus without any delay.

i All actively transmitting objects of the operating hours counter or the message objects"Load failure / overload", "short-circuit" and "Load type" are to be regarded as feedbackobjects. In this case, however, all feedbacks will always be transmitted with a delay,depending on the parameterisation for "Delay after bus voltage return".

i After bus voltage return, the message "Manual operation status" will only be transmittedactively to the bus ("0") if a manual operation, activated during a bus voltage failure, isended by the bus return. The status telegram is in this case transmitted without delay.

i Depending on the system, there is always a brief delay after programming with the ETS ifthe "Delay after bus voltage return" is configured to "0".

Delaying a feedbackOnly feedbacks that are enabled and set as actively transmitting can be configured with regardto the transmitting behaviour after bus voltage return.o Set the parameter "Time delay for feedback telegram after bus voltage return" to "Yes".

The parameter is on the parameter page of the corresponding switching status orbrightness value feedback of a dimming channel.In this case, after bus voltage return the feedback telegram is first transmitted to the busafter the end of the delay time. Alternatively (setting "No"), a feedback telegram istransmitted to the bus without time delay immediately after bus voltage return .

Page 52 of 157



4.2.4.1.4 Central functionThe actuator offers the possibility of linking selected individual or all dimming channels with a1-bit central communication object. The behaviour in case of activating a channel via the centralfunction is comparable to a central group address linked with all "Switching" objects.The dimming channels assigned to the central function are activated in accordance with thecentral object value received. The polarity of the central telegram can be configured as inverted.The behaviour of the channels is identical with the normal activation via the "Switch" objects.(same priority – last switching command is executed ). Thus, all 'downstream' functions, such astiming/supplementary functions, are also taken into account (Figure 11).

Figure 11: Function diagram "Central switching"

Enabling the central functiono Enable the central function on parameter page "General" by setting the "Central function ?"

to "Yes".If a function is active, the "Central switching" communication object is visible.

Assigning dimming channels to the central functionEach dimming channel can be assigned independently to the central function.The central function must have been enabled on parameter page "General". The assignmenthas otherwise no effect on a channel.o Set the Parameter "Assignment to central function ?" on parameter page "Kx General" (x

= number of dimming channel 1...4) to "Yes".The appropriate dimming channel is assigned to the central function. The connected loadscan be switched on or off centrally.

i The switching state set by the central function is tracked in the feedback objects and alsotransmitted to the bus, if these are actively transmitting. The switching state set by a centralfunction is not tracked in the "switching" objects.

i After a bus voltage return or after programming with the ETS, the central function is alwaysinactive (object value "0").

4.2.4.2 Channel-oriented functional description

4.2.4.2.1 Definition of the operating modeApart from controlling lighting, the universal dimmer actuator 1-gang can be used as a speedcontroller of single-phase electric motors. This operating mode can be preselected in the ETSand has a considerable effect on the parameter configuration and function of the device.In the function as a speed controller, the dimming principle is predefined to "phase cut-on".Consequently, no load type can then be configured in the ETS. Moreover, some parameter andobject texts change because the speed of a connected motor is controlled instead of brightnessin the "speed controller" operating mode. The speed (e.g. minimum speed) is configured in theETS as a percentage value. This value represents the dimming value in percent and is a gaugefor the output signal's phase angle of the actuator.The differences between the "speed controller" operating mode compared to the "lightingcontrol" operating mode can be read in detail in the chapter "Features in the speed controlleroperating mode" (see page 118).i The operating mode is not adjustable in the device variants "2-gang" and "4-gang". The

lighting operation is always intended here.

Presetting the mode of operationThe operating mode of the dimming channel is set on the "K1 - General" parameter page .o Set the "operating mode" parameter to "Lighting control".

Lighting is connected on the dimmer output. The device permits switching and dimming ofHV incandescent lamps, HV halogen lamps and LV halogen lamps with inductivetransformers or Tronic-Transformers by means of conventional transformers and Tronic-Transformers. When using the application program with the version "1.2" in conjunctionwith devices of the generation "V02", it is also possible to activate dimmable HV-LEDs orcompact fluorescent lamps.The appropriate dimming procedure can either be calibrated automatically, or alternatively,configured in the ETS (see "Type of connected load" parameter).

o Set the "operating mode" parameter to "speed controller".An electric motor is connected on the dimmer output. The device enables the motor to bestarted up and switched off as well as the variation of the speed. The appropriate dimmingprocedure in this case is preselected automatically and cannot be altered.

i In the as-delivered state of the device, the "lighting control" is preconfigured as operatingmode. When connecting a motor, the "speed controller" operating mode must beconfigured in the ETS. After the installation, commissioning using the ETS is essentialbefore switching on the mains voltage supply (see page 16-17).

4.2.4.2.2 Definition of the load type and load type messageThe device works according to the phase cut-on or phase cut-off dimming principle and permitsswitching and dimming of HV incandescent lamps, HV halogen lamps and LV halogen lamps bymeans of conventional transformers and Tronic-Transformers. When using the applicationprogram with the version "1.2" in conjunction with devices of the generation "V02", it is alsopossible to activate dimmable HV-LEDs or compact fluorescent lamps. The "1-gang" devicevariant can also control single-phase electric motors in the "Speed controller" operating mode.In lighting operation, the characteristic of the connected load can automatically be calibratedseparately for each dimming channel and the appropriate dimming procedure can be set.Alternatively, the dimming procedure can be predefined by a parameter in the ETS withoutcalibration taking place. This procedure is necessary for loads that do not enable automaticcalibration (e.g. with HV-LED lamps or compact fluorescent lamps).i In the "Speed controller" operating mode, the dimming principle is preset to "phase cut-on".i When selecting the appropriate dimming principle, the specifications of the lamp

manufacturer should generally be observed!

Defining load typeThe "Type of connected load" parameter on the parameter page "Kx General" (x = number ofdimming channel 1...4) defines the dimming procedure. This parameter is not available in the"speed controller" operating mode for the "1-gang" device variant).


CAUTION!Danger of destruction from mixed loads.The dimmer and load may be destroyed.Do not connect capacitive loads, e.g. electronic transformers, and inductiveloads, e.g. inductive transformers, together on the same dimmer output.Do not connect inductive transformers together with HV LED lamps or compactfluorescent lamps on the same dimmer output.

o Set the parameter to "universal (with calibration procedure)".The dimming channel calibrates itself universally to the connected load type. Afterprogramming in the ETS, after bus voltage return, after mains voltage return on the terminalpair "L N" (without bus voltage) or after switching on the mains voltage supply of a loadoutput, the actuator calibrates itself automatically to the connected load. The calibrationprocedure becomes noticeable during ohmic loads by a brief flicker and lasts up to 10seconds depending on the network conditions.

i This setting must not be selected for loads that do not enable automatic calibration (e.g.with HV-LED lamps or compact fluorescent lamps). In this case, a suitable dimmingprinciple must be preselected (see following settings).

o Set the parameter to "electronic transformer (capacitive / phase cut-off)".The dimming channel is preset to phase cut-off principle. There is no automatic calibrationof the load type. Ohmic loads or electronic transformers can be connected to the output.

Page 55 of 157



o Set the parameter to "conventional transformer (inductive / phase cut-on)".The dimming channel is preset to phase cut-on principle. There is no automatic calibrationof the load type. Conventional transformers can be connected to the output.

o Only with application program version "1.2" and device generation "V02": Set theparameter to "LED (phase cut-off)".The dimming channel is preset to an optimized phase cut-off principle. There is noautomatic calibration of the load type. HV LED or compact fluorescent lamps optimized forthis dimming principle can be connected to the output.

o Only with application program version "1.2" and device generation "V02": Set theparameter to "LED (phase cut-on)".The dimming channel is preset to an optimized phase cut-on principle. There is noautomatic calibration of the load type. HV LED or compact fluorescent lamps optimized forthis dimming principle can be connected to the output.

i The settings "LED (phase cut-off)" and "LED (phase cut-on)" are only available in theapplication program with version "1.2" and are only evaluated by devices that contain theversion designation "V02" on the device label (see page 35). If the application program"1.2" is used with these settings in old devices (no designation or designation "V01"), noactuation of HV-LED or compact fluorescent lamps is possible! The devices then setthemselves to simple phase cut-off or phase cut-on.Application programs with the version "1.1" can be programmed in devices with designation"V02". Actuation of HV LED and compact fluorescent lamps is not possible in this caseeither!

i In the as-delivered state of the device, the dimming principle is set to "universal" for alloutputs.

i When changing a load type on an output, the dimming principle must also be changed ifnecessary (see page 14)!

The specifications of the lamp manufacturer can be observed in order to obtain the appropriatedimming principle for the connected lamps. The following table shows dimming principlecombinations and connected load that are appropriate, not recommended and inappropriate.

Page 56 of 157



Figure 12: Parameter selection "type of connected load" depending on activated load type

i Dimming results and dimming quality could vary depending on cable lengths, gridconditions and other influencing factors. Depending on the design and power rating of thelamps, the connected load of the specified values could vary. We do not assume anyresponsibility for the function, dimming results and dimming quality in connection with HVLED and will not accept any liability.

Recommendation for the configuration of the dimming principle with LED lamps:It is recommendable to operate LED lamps preferably in the load type "LED phase cut-off"regardless of the manufacturer's specification. The advantage of this setting lies in the fact thata dimming output can provide the maximum LED nominal load (see technical data). This is oftennot possible in phase cut-on principle. Only configure the type of load in the ETS to "LED phasecut-on" if the operation of the connected lamps in the phase cut-off principle is not satisfactory(e.g. dimming range is too small).Protection functions (over-voltage switch-off) ensure that the device is not destroyed if theconnected LED lamps are controlled in a dimming principle that the manufacturer has notdesigned them for (see page 27).

Problem resolution with LED lamps:Possible problems during operation of LED lamps and their remedial measures aredemonstrated in the following...

Parameter setting "LED phase cut-off" ->Problems:- Dimming range too small- Minimum brightness too high- Lamps flicker- Output switches off due to overvoltageRemedial action:Check operation in the phase cut-on, reduce connected load as well if necessary, exchangelamps for another type.

Page 57 of 157



Parameter setting "LED phase cut-on" ->Problems:- Lamps flicker- Dimmer actuator overheats (output switches off due to overtemperature)- Dimmer actuator humsRemedial action:Reduce connected load, check operation in the phase cut-off, exchange lamps for another type.

Enabling feedback of the load typeThe device permits feedback of the set or calibrated load type to the bus. In this way, it ispossible to identify the dimming principle according to which the dimming channel is working,even without knowing the parameter setting in the ETS. In universal operation, it is also possibleto detect whether the channel has calibrated itself to phase cut-on or phase cut-off operation.Feedback of the load type is provided using the 1-byte object "Signal load type" available ineach dimming channel. The object has the value encoding shown in the following table.

Objectvalue

Meaning

0 Load type undefined (mains voltage off / short-circuit etc. /no calibrationpossible)

1 Load type capacitive / ohmic / LED phase cut-off (set by parameter in the ETS )

2 Load type inductive / LED phase cut-on (set by parameter in the ETS )

3 Load type universal, successful calibration to capacitive or ohmic load

4 Load type universal, successful calibration to inductive load

5...255 Not used

Value encoding of the object "Signal load type"

o Set the parameter "Signal load type ?" on parameter page "Kx Enabled functions" (x =number of dimming channel 1...4) to "Yes".The telegram feedback of the load type is enabled and activated. After bus voltage return,in the case of mains voltage failure on the load and after programming in the ETS, themessage telegram is transmitted actively to the bus. With the load type "universal" thetelegram is additionally transmitted after each new calibration procedure (e.g. after loadfailure / overload or short-circuit).

i It should be noted that after programming in ETS, after switching on the bus voltage ormains voltage supply of the device, the "Delay after bus voltage return" configured in theETS must have elapsed before a load type message telegram is transmitted to the bus.

i In the "speed controller" operating mode for the "1-gang" device variant the "inductive" loadtype is always signalled if the signalling object is enabled.

Page 58 of 157



4.2.4.2.3 Signalling short-circuitShort-circuit protection is integrated in the device for each output. If the device detects a short-circuit, the load is switched off automatically after 7 seconds in phase cut-off operation(capacitive and ohmic loads) or after 100 milliseconds in phase cut-on operation (inductiveloads). After switching off, the actuator transmits a message telegram "Short-circuit present – 1"to the bus for the dimming channel concerned, if this message is enabled in the ETS.Here, it is described how a short-circuit message is enabled and how the telegram transmissionof this message behaves. The chapter "Fitting and electrical connection" describes in detail howto eliminate a short-circuit fault (see page 24-25).

Enabling a short circuit signalFeedback of a short-circuit is provided using the 1 byte object "Signal short-circuit" available ineach dimming channel. Using the "Signal short-circuit ?" parameter, the object can be enabledon parameter page "Kx – Enabled functions" (x = number of the dimming channel 1...4).o Set the parameter to "Yes".

The short-circuit message is enabled and activated. After identifying a described fault, a"Short-circuit detected – 1" message telegram is sent to the bus from the actuator.

i In the event of a short-circuit message, the actuator sets the switching status to "OFF" andthe status of the brightness value to "0" and transmits these values to the bus if enabled inthe ETS.

i When switching on the mains voltage on the load after eliminating the fault, the actuatortransmits a message telegram "no short-circuit – 0" to the bus after 7 seconds in phase cut-off operation and after 100 milliseconds in phase cut-on operation. Otherwise, a short-circuit message is transmitted again.

i The actuator initialises the objects "Signal short-circuit" of all dimming channels after anETS programming operation or after switching on the bus voltage according to their currentstatus. In this case, it should be noted that the "Delay after bus voltage return" configured inthe ETS must have elapsed before short-circuit message telegrams are transmitted to thebus.

Page 59 of 157



4.2.4.2.4 Signalling load failure / overloadThe device with a lighting control can monitor the electric circuits of its load outputs independentof each other. The actuator detects the mains voltage supply failures (> 15 seconds) of anoutput or the interruption of the electric circuit when a load is switched on or off. The load failuredetection can be enabled separately in the ETS for each dimming channel.If there is an overtemperature in the device, the load is switched off by the temperature controlof the device. The actuator, 15 seconds after switching off, transmits a message telegram "Loadfailure present – 1" to the bus for the dimming channel concerned, if this message is enabled inthe ETS. In this state, the dimming channel concerned can no longer be switched on by manualor bus control. To reset such a fault, it might be necessary to switch off the mains voltage supplyof the load outputs. Over-temperatures in the device either occur as a result of self-heating(electrical overload) or external influences (ambient temperature in the control cabinet is toohigh).The device is also protected against electrical overload. Electrical overloads occur when thenominal operation parameters of a dimmer output are exceeded temporarily or continuously.The reaction of a device then depends on how great the electrical overload is and whichambient conditions prevail.If the overload exceeds the defined short-circuit threshold, the device switches off the dimmingchannel concerned after 7 seconds at the latest, depending on the load type. In this case, theactuator generates a short-circuit message (see page 59) on the bus if this feedback is enabledin the ETS.If the electrical overload does not exceed the short-circuit threshold, the device heats upcontinuously. Whether and how rapidly this self-heating occurs depends essentially on howgreat the overload is and how much the device is thermally influenced from outside. The heatingup of the device causes the over-temperature switch-off to take effect from a specifictemperature threshold. In this case, the actuator generates a load failure message on the bus ifthis feedback is enabled in the ETS.Consequently, the device protects itself constantly by means of short-circuit or over-temperatureswitch-off even in the case of an electrical overload.Here, it is described how a load failure/overload message is enabled and how the telegramtransmission of this message behaves. The chapter "Fitting and electrical connection" describesin detail which events cause a load failure or overload and how to eliminate these faults (seepage 23).

i No message of a load failure is possible with the device variant "speed controller" operatingmode in the "1-gang" and device variant "4-gang" and "parallel wired outputs" (only inapplication program version "1.1"). No load failure message can be configured in the ETSin this case.

Enabling the signalling of a load failure / overloadFeedback of a load failure or overload is provided using the 1 bit object "Signal load failure /overload" available in each dimming channel. Using the "Signal load failure / overload ?"parameter, the object can be enabled on parameter page "Kx – Enabled functions" (x = numberof the dimming channel 1...4).o Set the parameter to "Yes".

The load failure/overload message is enabled and activated. A message telegram "Loadfailure/overload detected – 1" is transmitted from the actuator to the bus approx.15 ...20 seconds after identification of a load failure or overload. A mains voltage failure ofthe output is always detected as load failure if the mains voltage failure lasts longer thanapprox. 15 seconds.

i In the event of a load failure or overload, the actuator sets the switching status to "OFF"and the status of the brightness value to "0" and transmits these values to the bus ifenabled in the ETS.

Page 60 of 157



i The actuator initialises the objects "Signal load failure / overload" of all dimming channelsaccording to their current status after an ETS programming operation or after switching onthe bus voltage. In this case, it should be noted that the "Delay after bus voltage return"configured in the ETS must have elapsed before load failure/overload message telegramsare transmitted to the bus.

i At least 15 seconds after switching on the mains voltage, the actuator transmits a messagetelegram "no load failure / no overload – 0" to the bus if the fault was eliminated. Otherwise,a load failure/overload message is transmitted again. No message telegram is transmittedwithin the "Delay after bus voltage return".

4.2.4.2.5 Definition of the brightness range

The brightness range, adjustable by switching or dimming procedures, can be limited bydefining a lower and upper brightness value. The lower brightness value is either defined by thebasic brightness, or alternatively, by the minimum brightness. The upper brightness value isalways characterised by the maximum brightness.The maximum brightness adjustable in the ETS is never exceeded in the switched-on operatingstate of a dimming channel under any circumstances. Neither when switching on nor whendimming. The maximum brightness value can be reduced for energy saving reasons, forexample. In combination with some power extensions, it may also be necessary to reduce themaximum brightness (please observe the documentation of the power extensions and notes inthe chapter "Fitting and electrical connection" in this documentation!).Furthermore, the brightness value, which should be set whenever switching on via the"switching" or "central switching" object or by manual operation on the dimming channel, can bepredefined. This switch-on brightness must always be between the upper and lower brightnesslimit value of the dimming range.The adjustable characteristics of the lower brightness value in the ETS differ as follows...

- Definition of the lower brightness limit with basic brightness (Figure 13):The "basic brightness" parameter of the parameter page "Kx – General" (x = Number of thedimming channel 1...4) predefines the lower brightness threshold by adapting to the lamps.The basic brightness can be set to one of 8 step values and is a gauge for the minimumadjustable residual phase angle of the output signal in relation to the decimal brightnessvalues "1", "2" and "3" (percentage: ~0.4 ... 1 %). The basic brightness can be undershotonly by switching off.The configurable basic brightness enables the dimming signal to be adjusted in thesmallest possible dimmer setting to the lamp used. The basic brightness should be set to astep value at which the lamp at the smallest brightness value will still light up at anadequate level of brightness so that it is detected as switched on. A recommendation forincandescent lamps and standard halogen lamps is given in the ETS as an adjustment aid.

Figure 13: Example of a brightness range with basic brightness

- Definition of the lower brightness limit with minimum brightness (Figure 14):The "minimum brightness" parameter of the parameter page "Kx – General" (x = Number ofthe dimming channel 1...4) predefines a lower brightness threshold in the percentagerange 1 % ... 45 % (decimal "3" ... "115") in stages. The minimum brightness cannot beundershot in any switched-on operating state of the dimming channel. An undershot is onlypossible by switching off.The brightness of the controlled lamps can be adapted individually – even to the brightnesssensitivity of the human eye - by using the minimum brightness.

Page 62 of 157



Figure 14: Example of a brightness range with minimum brightness

i In the "speed controller" operating mode for the "1-gang" device variant - similar to thedescription of the brightness values for lighting control in this chapter - the minimum speedcan be configured in the ETS (Figure 14). The alternative configuration of a basic speed isnot provided here for technical reasons. The maximum speed cannot be adjusted bymeans of a parameter either. It is predefined to 100 %. The cutting-in speed is unalterablypreselected to a maximum speed (100 %).The differences between the "speed controller" operating mode compared to the "lightingcontrol" operating mode can be read in detail in the chapter "Features in the speedcontroller operating mode" (see page 118).

Adjusting basic brightnessThe basic brightness can be set separately for each dimming channel.The "Definition of the brightness range" parameter is configured to "with basic brightness".o Set the "basic brightness" parameter on parameter page "Kx General" (x = number of

dimming channel 1...4) to the required step value.The set step value, which is a gauge for the smallest adjustable residual phase angle of theoutput signal, is set to the decimal brightness values "1", "2" and "3" and therefore cannotbe undershot in any switched-on operating state of the dimming channel.

i The parameter should be set in such a way that the lamp will still light up at the lowestdimmer setting.

i When operating a Universal Power booster on the dimmer output (see parameter"Operation with universal power booster ?") the level 1" can be set but has no effect. If theparameter should be set to level 1 in this case, the device executes level 2 as basicbrightness.

Setting the minimum brightnessThe minimum brightness can be set separately for each dimming channel.The "Definition of the brightness range" parameter is configured to "with minimum brightness".o Set the "minimum brightness" parameter on parameter page "Kx General" (x = number of

dimming channel 1...4) to the required brightness value.The set brightness is not undershot in any switched-on operating state.

i The selection of the adjustable value is upwardly limited to 45 %. Greater values cannot beconfigured because otherwise the adjustment range of the maximum brightness will be cut(minimum brightness < maximum brightness).

Page 63 of 157



i The ETS does not check all configured brightness values of a channel during the editing ofthe minimum brightness (e.g. switch-on brightness, scene values)! If values that aresmaller than the configured minimum brightness are predefined by the ETS configuration,the actuator sets the minimum brightness as brightness value later during operation. Thesame holds true if the actuator receives values via the brightness object during operation,which undershoots the minimum brightness.

Setting the maximum brightnessThe maximum brightness can be set separately for each dimming channel.o Set the "maximum brightness" parameter on parameter page "Kx General" (x = number of

dimming channel 1...4) to the required brightness value.The set brightness is not undershot in any switched-on operating state of the dimmingchannel.

i The selection of the adjustable value is downwardly limited to 50 % when using a minimumbrightness. Smaller values cannot be configured in this case because otherwise theadjustment range of the minimum brightness will be cut (minimum brightness < maximumbrightness).

i The ETS does not check all configured brightness values of a channel during the editing ofthe maximum brightness (e.g. switch-on brightness, scene values)! If values that aregreater than the configured maximum brightness are predefined by the ETS configuration,the actuator sets the maximum brightness as brightness value later during operation. Thesame holds true if the actuator receives values via the brightness object during operation,which exceed the maximum brightness.

i When extending the power of an output of a dimming channel from our company by meansof universal power extensions, the maximum brightness (ETS parameter) must be reducedto 90 % at most!

Setting the switch-on brightnessThe switch-on brightness can be set separately for each dimming channel.o Set the "switch-on brightness" parameter on parameter page "Kx General" (x = number of

dimming channel 1...4) to the required brightness value.The set brightness is set after receipt of an ON telegram via the "Switching" communicationobject or by switching on by the manual operation on the dimming channel. Furthermore,the configured switch-on brightness is set with the "activated" polarity after receipt of acentral telegram.

o Alternatively, set the parameter "Switch-on brightness" to "Memory value (brightnessbefore switching off last time)".When switching on, the active and internally saved brightness value prior to switching offlast time is set (via the "switching" or "central switching" object). After programming with theETS, the value is predefined to maximum brightness. Only a bus voltage failure will notdelete the memory value, however.

i If the configured switch-on brightness is greater than the configured maximum brightness,the actuator sets the maximum brightness as the new brightness value for the dimmingchannel concerned when switching on (minimum brightness < switch-on brightness <maximum brightness).

i A memory value is also then saved internally by a switch-off telegram if the bus-controlledswitch-off is overridden, for example, by a disable or forced position function or by amanual operation. In this case, the internally tracked brightness value is saved as memoryvalue.

Page 64 of 157



i If no soft ON function is activated, the brightness value is jumped to when switching on.Once a soft ON function is activated, the switch-on brightness is dimmed according to thedimming speed for the soft ON function.

i The switch-on speed is not configurable in the "speed controller" operating mode for the"1-gang" device variant. Additional differences between the "speed controller" operatingmode compared to the "lighting control" operating mode can be read in detail in the chapter"Features in the speed controller operating mode" (see page 118).

Operation with universal power boosterTo increase the connected load, Universal power boosters can be connected to the device.Universal power boosters are devices that supply themselves with energy directly viacomponents of the dimmer actuator's output signal (no neutral conductor connection available).To ensure failure-free operation, the dimmer actuator output signal must be adapted in such away that a certain amount of residual phase angle still remains (residual cut-on or off) for thehighest dimming position. This residual phase angle must be large enough to enable universalpower boosters to supply themselves with energy.

Only for program version "1.2" and device generation "V02":If the output power is increased by means of universal power boosters, the correspondingchannel configuration of the dimmer actuator must be adapted in the ETS. Based on the settingof the parameter "Operation with universal power booster ?" the dimmer actuator adjusts theoutput signal for using universal power boosters automatically.o Set the parameter to "No".

No universal power booster is connected to the dimming channel. In the highest dimmingposition (100 % brightness value), the smallest possible residual phase angle is set on thedimmer output. As a result, the connected lighting is set to the maximum lighting leveltechnically possible.

o Set the parameter to "Yes".At least one universal power booster is connected to the dimming channel. In the highestdimming position (100 % brightness value), a residual phase angle necessary for universalpower boosters is set on the dimmer output. The output signal cut-on or cut-off in this waycorresponds to a resulting brightness of approx. 90 % compared to an identicallyconstructed dimmer actuator without a power booster. The dimmer actuator rescales theadjustable brightness range automatically for the corresponding channel so that apresetting and feedback within a range of 0…100% is still possible.

Only for application program version "1.1" or device generation without version designation:It is not possible to operate the device with universal power boosters in conjunction withelectronic transformers! Please use Tronic power boosters for power extension when operatingelectronic transformers.When extending the power of an output by means of universal power boosters, the maximumbrightness (ETS parameter) should be reduced to 90 % at most!

Only for program version "1.1" or device generation "V01":When extending the power of an output by means of universal power boosters, the maximumbrightness (ETS parameter) should be reduced to 90 % at most!

i Visible brightness differences between the lighting on a dimmer actuator output withoutpower booster and a dimmer actuator with power booster are possible.

i Choose power boosters that are suitable for the dimmer and load! For additionalinformation, please always refer to the instructions for the power extensions in question.

Page 65 of 157



i When using conventional power boosters for phase cut-on or phase cut-off principle (NV orTRONIC power boosters) it is not normally necessary to adapt the output signal of thedimmer actuator.

i If HV-LED and compact fluorescent lamps are connected to a dimmer output, a powerextension by power boosters is generally not possible!


i With the "1-gang" device variant, it is not permitted to connect additional power extensionsto the power output. Consequently, the parameterisation of universal power boosters is notnecessary in this case.

i The parameter "Operation with universal power booster ?" is only available in theapplication program with version "1.2" and is only evaluated by devices that contain theversion designation "V02" on the device label (see page 35). If the application program"1.2" with the setting "Operation with universal power booster ? = Yes" is used in old device(no designation or designation "V01"), the actuator does not carry out any automaticadjustment of the residual phase angle! Here, the maximum brightness must be configuredmanually to a lower brightness value in the parameterisation so that universal powerboosters can work failure-free.Application programs with the version "1.1" can be programmed in devices with designation"V02". In this case, too, the maximum brightness must be configured manually to a lowerbrightness value in the parameterisation so that universal power boosters can work failure-free.

4.2.4.2.6 Response after a device resetThe switching states or brightness values of the dimming channels after a bus voltage failure,bus or mains voltage return or after ETS programming can be preset separately.i In the "speed controller" operating mode for the "1-gang" device variant - similar to the

description of the brightness values for lighting control in this chapter - the speed valuescan be configured in the ETS. The differences between the "speed controller" operatingmode compared to the "lighting control" operating mode can be read in detail in the chapter"Features in the speed controller operating mode" (see page 118).

Presetting the behaviour after ETS programmingThe parameter "Behaviour after ETS programming" is preset separately for each dimmingchannel on the parameter page "Kx General" (x = number of the dimming channel 1...4). Thisparameter can be used to configure the brightness behaviour of a channel irrespective of thebehaviour after a bus or mains voltage return.o Set the parameter to "no reaction".

After an ETS programming operation, the dimming channel shows no response andremains in the switching brightness state currently selected or is switched off.

o Set the parameter to "switch off".The dimming channel is switched off after a programming in the ETS.

o Set parameter to a brightness value.The dimming channel is set to the predefined brightness value. It is important that theconfigured value does not undershoot the set minimum brightness (if present) or exceedthe maximum brightness.

i The configured behaviour will be executed after every application or parameter downloadby the ETS. A simple download of the physical address alone or partial programming ofonly the group addresses has the effect that this parameter is disregarded and that theconfigured "Behaviour after bus or mains voltage return" will be executed instead.Furthermore, the behaviour will only then be executed if the bus and mains voltage areswitched on after programming.

i An ETS programming operation can also be performed without mains voltage. The mainsvoltage supply is not required for an ETS download.

i The actuator briefly initialises after each ETS programming operation. Dimming channelswhose load type is configured to "universal" calibrate themselves to the load. Thecalibration procedure becomes noticeable during ohmic loads by a brief flicker and lasts upto 10 seconds depending on the network conditions.

i A switching state and brightness value set after an ETS programming cycle is added to thefeedback objects. Actively transmitting feedback objects also only first transmit after anETS programming cycle when the initialisation has finished and, if necessary, the "delaytime after bus voltage return" has elapsed.

i In the "no reaction" setting: After the programming operation, a brief switch-off occursduring the initialisation phase of the actuator. Afterwards, the brightness value that wasactive before is then reset again.

i An active manual mode will be terminated by an ETS programming operation.i After an ETS programming operation, the disabling functions and the forced-positions are

always deactivated. The brightness values and forced position objects saved in case of thebus voltage failure are deleted.

Page 67 of 157



Presetting the behaviour in case of bus voltage failureThe parameter "Behaviour in case of bus voltage failure" can be preset separately for eachdimming channel under "Kx - "General" (x = number of dimming channel 1...4).o Set the parameter to "no reaction".

In case of bus voltage failure, the dimming channel shows no reaction and remains in thecurrently set brightness state, provided that the mains voltage on the dimming outputs isstill switched on.

o Set the parameter to "switch off".The dimming channel is switched off in the case of bus voltage failure. It should be notedthat the configured OFF command can only be executed if the mains voltage supply of theactuator (terminal pair "L N") is switched on. If the mains voltage is switched off, theactuator in this configuration shows no reaction (the last brightness state remains active)provided that the mains voltage on the dimming outputs is still switched on.

o Set parameter to a brightness value.The dimming channel is set to the predefined brightness value. It should be noted that thebrightness value can only be set if the mains voltage supply of the actuator (terminal pair "LN") is switched on. If the mains voltage is switched off, the actuator in this configurationshows no reaction (the last brightness state remains active) provided that the mainsvoltage on the dimming outputs is still switched on.The configured value must not undershoot the set minimum brightness (if present) orexceed the maximum brightness.

i Active disabling functions or forced position functions are cancelled and remain inactiveuntil they are reactivated.

i In case of a bus voltage failure, the current states of the forced-positions are also saved sothat they can be tracked on return of bus voltage if necessary (depending on theparameterization of the forced positions).

i In case of a bus voltage failure, the current brightness values of all dimming channels arepermanently saved internally so that these brightness values can be reset after bus voltagereturn or mains voltage return (without bus) if this is configured in the ETS. The data arestored before the reaction parameterized for the case of bus voltage failure takes place andonly if one part of the supply (mains or bus) is still present, or if the supply fails completelyafter the bus / mains voltage has been available before without interruption for at least 20seconds after the last reset (storage capacitors sufficiently charged for storage purposes).In all other cases nothing is stored (Brightness value = "0")!

The saving process is performed only once after the failure of one part of the supplyvoltage...Bus voltage failure -> Data storage -> Then mains voltage failure -> No further datastorage.

Because the brightness values are saved only once in the event of bus voltage failure,values that are changed after a bus voltage failure, for example via manual control, are nottracked!

i If the bus voltage fails while a manual operation on the device is activated, the parameter"Behaviour in case of bus voltage failure" is not executed.

Behaviour after bus or mains voltage return presettingThe parameter "Behaviour after bus or mains voltage return" can be preset separately for eachdimming channel on the parameter page "Kx General" (x = number of the dimming channel1...4). This parameter will always be executed on return of bus voltage only if the mains voltage(without bus) is switched on. If the mains voltage is switched on when the bus voltage ispresent, the actuator does not execute any particular reaction.o Set the parameter to "no reaction".

Page 68 of 157



After bus or mains voltage return, the dimming channel shows no response and remains inthe brightness state currently selected or is switched off.

o Set the parameter to "switch off".The dimming channel is switched off after bus/mains voltage return.

o Set parameter to a brightness value.The dimming channel is set to the predefined brightness value. It is important that theconfigured value does not undershoot the set minimum brightness (if present) or exceedthe maximum brightness.

o Set parameter to "brightness value before bus voltage failure".After bus or mains voltage return, the brightness value last set before bus voltage failureand internally stored on bus voltage failure will be tracked.

o Set parameter to "Activate staircase function" "Activate time dimmer function".The staircase function / time dimmer function is – irrespective of the "Switching" object -activated after bus or mains voltage return. With this setting, make sure that the staircasefunction / time dimmer function is also enabled in the configuration of the dimming channel.When the function is not enabled, there is no reaction after bus/mains voltage return withthis setting.

i In all settings: When the bus voltage is switched on, the brightness value is set to "0 %" ifno mains voltage is switch on at the time of bus voltage return on the load outputs.

i Setting "brightness value as before bus/mains voltage failure": An ETS programmingoperation of the application or the parameter resets the stored switching state to "off - 0".

i In the "No reaction" setting: On return of bus voltage with permanently switched on mainsvoltage, the corresponding dimming channel shows no response and remains in thebrightness state last selectedWhen the bus voltage is switched on (without switching on the bus voltage), the actuatorsets the brightness value "0" on the corresponding channels.

i The actuator briefly initialises after switching on the mains voltage each time. Dimmingchannels whose load type is configured to "universal" calibrate themselves to the load. Thecalibration procedure becomes noticeable during ohmic loads by a brief flicker and lasts upto 10 seconds depending on the network conditions.

i A switching state and brightness value set after bus voltage return is tracked in thefeedback objects. Actively transmitting feedback objects first transmit, however, after bus ormains voltage return when the initialisation of the actuator has finished, and if necessarythe "delay time after bus voltage return" has elapsed.

i In the case of forced position as supplementary function: The communication object of theforced position can be initialised separately after bus voltage return. This has an effect onthe reaction of the dimming channel when the forced position is activated. The configured"Behaviour in the case of bus or mains voltage return" will only be executed if no forcedposition is activated after bus voltage return.

i In the case of enabling function as supplementary function: Active disabling functions arealways inactive after bus voltage return.

i After return of bus voltage a manual control will be interrupted..

4.2.4.2.7 Feedback for switching status and brightness value

The actuator can track the current switching state and brightness value of a dimming channelvia separate feedback objects and can also transmit them to the bus, if the bus voltage is on.The following feedback objects can be enabled independently of each other for each channel ... - Feedback switching status (1 bit)- Feedback brightness value (1 byte)

The actuator calculates the object value of the feedback objects during each switching ordimming procedure. The actuator tracks the switching state or brightness value and updates thefeedback objects even when a dimming channel is activated by the manual operation or scenefunction.

The switching status feedback object is updated after the following events...- Immediately after switching on a dimming channel (if necessary, first after a switch-on

delay has elapsed and at the beginning of a soft ON dimming procedure / also after astaircase function).

- After switching off a dimming channel (if necessary, first after a run-on-time has elapsedand at the end of a soft OFF dimming procedure / also after a staircase function).

- Immediately after switch-off by the automatic switch-off function.- At the beginning of a dimming procedure when dimming on (relatively high dimming or

brightness value = 1…100 %) a dimming channel.- At the end of a dimming procedure when dimming off (brightness value = 0 %) a dimming

channel.- Only when the switching state changes (therefore not for dimming procedures that do not

change the switching state e.g. from 10 % to 50 % brightness).- During updating of the switching state from "ON" to "ON" when the dimming channel is

already switched on.- During updating of the switching state from "OFF" to "OFF" when the dimming channel is

already switched off.- Always at the start or end of a disabling or forced position function (only if the switching

state changes as a result).- Always after bus voltage return, in the case of mains voltage failure ("OFF") or at the end of

any ETS programming process (if necessary also delayed and after calibration of the load).

The brightness value feedback object is updated after the following events...- At the end of a relative (4-bit) or absolute (1-byte) dimming procedure.- After switching on a dimming channel, if the switch-on brightness is set (if necessary, first

after a switch-on delay has elapsed and at the end of a soft ON dimming procedure / alsoafter a staircase function).

- After switching off a dimming channel (if necessary, first after a run-on-time has elapsedand at the end of a soft OFF dimming procedure / also after a staircase function).

- Immediately after switching off by means of the automatic switch-off function.- Only if the brightness value changes (if a brightness value specification undershoots the

minimum brightness as a result of relative or absolute dimming from outside or exceeds themaximum brightness, the actuator does not update a brightness value feedback accordingto the minimum brightness or maximum brightness).

- Always at the start or end of a disabling or forced position function (only if the brightnessvalue changes as a result).

- Always after bus voltage return, in the case of mains voltage failure ("0") or at the end ofany ETS programming process (if necessary, also delayed and after calibration of the load)

i In the "speed controller" operating mode for the "1-gang" device variant - similar to thedescription of the brightness values for lighting control in this chapter - the speed valuescan be configured in the ETS. The differences between the "speed controller" operatingmode compared to the "lighting control" operating mode can be read in detail in the chapter"Features in the speed controller operating mode" (see page 118).

Figure 15: Functional feedback diagram of the feedbacks

i In the case of enabling function as supplementary function: A 'flashing' dimming channel isalways signalled back as "switched on" and with switch-on brightness. Switching statusfeedbacks are also transmitted for disabled channels when the channels are readjusted bya manual operation, for example.

Activating switching status feedbackThe switching status feedback can be used as an active message object or as a passive statusobject. As an active message object, the switching status feedback information is also directlytransmitted to the bus whenever the feedback value is updated. As a passive status object,there is no telegram transmission after an update. In this case, the object value must be readout. The ETS automatically sets the object communication flags required for proper functioning.The parameter "Feedback switching status ?" can be preset separately for each dimmingchannel under "Kx - "feedbacks" (x = number of the dimming channel 1...4).The feedbacks must be enabled on parameter page "Kx - Enabled functions".o Set the parameter to "feedback object is active signalling object".

The "Switching feedback" object is enabled. The switching status is transmitted once thestatus is updated. An automatic telegram transmission of the feedback takes place afterbus voltage return or after programming with the ETS.

Page 71 of 157



o Set the parameter to "feedback object is passive status object".The "Switching feedback" object is enabled. The switching status will be transmitted inresponse only if the feedback object is read out from by the bus. No automatic telegramtransmission of the feedback takes place after bus voltage return or after programming withthe ETS.

o Set the parameter to "no reaction".The switching status feedback is deactivated.

i Feedback of the current switching status via the "switching" object is not possible.

Presetting update of the switching status feedbackIn the ETS you can specify when the actuator should update the feedback value for theswitching status in case of an actively transmitting communication object. The object valueupdated by the actuator is then signalled actively to the bus.The parameter "Upgrade of the object value for feedback of switching status" can be presetseparately for each dimming channel on the parameter page "Kx - "feedbacks" (x = number ofthe dimming channel 1...4).The feedbacks must be enabled on parameter page "Kx - Enabled functions". In addition, theswitching status feedback must either be configured to actively transmitting or passivelyreadable.o Set the parameter to "after each update obj. 'Switching'/'Central'".

The actuator updates the feedback value in the object once a new telegram is received onthe input objects "Switching" or "Central switching". With an actively transmitting feedbackobject, a new telegram is also then actively transmitted to the bus each time. The telegramvalue of the feedback does not necessarily have to change. Hence, a correspondingswitching status feedback is also generated on the "Switching" object such as in the caseof cyclical telegrams.

o Set the parameter to "only if the feedback value changes".The actuator only updates the feedback value in the object if the telegram value (e.g. "OFF"to "ON") also changes. If the telegram value of the feedback does not change (e.g. in thecase of cyclical telegrams to the "Switching" object with the same telegram value), thefeedback then remains unchanged. Consequently, with an actively transmitting feedbackobject, no telegram with the same content will be transmitted repeatedly either.This setting is recommendable, for instance, if the "Switching" and "Switching feedback"objects are linked to an identical group address. This is often the case when activating bymeans of light scene push-button sensors (recall and storage function).

Activating switching status feedback on return of bus voltage or after programming withthe ETSIf used as active message object, the switching status feedback information is transmitted to thebus after bus voltage return or after programming with the ETS. In these cases, the feedbacktelegram can be time-delayed with the delay being preset globally for all dimming channelstogether (see page 52).o Set the parameter "Time delay for feedback after bus voltage return ?" on parameter page

"Kx Feedbacks" (x = number of dimming channel 1...4) to "Yes".The switching status telegram will be transmitted with a delay after bus voltage return orafter programming with the ETS. No feedback telegram is transmitted during a runningdelay, even if the switching state changes during this delay.

o Set the parameter "Time delay for feedback after bus voltage return ?" on parameter page"Kx Feedbacks" (x = number of dimming channel 1...4) to "No".

Page 72 of 157



The switching status telegram will be transmitted immediately after bus voltage return orafter programming with the ETS.

i After programming with the ETS, the switching status feedback is always transmitted with abasic delay of a few seconds (initialisation procedure of the actuator / possibly calibration ofthe load types). The basic delay is added to the "Delay after bus voltage return" configuredin the ETS, if activated.

Presetting the cyclical transmission function for the switching status feedback telegramThe switching status feedback telegram can also be transmitted cyclically via the activemessage object in addition to transmission after updating.o Set the parameter "Cyclical transmission of feedback telegram?" on parameter page "Kx

Feedbacks" (x = number of dimming channel 1...4) to "Yes".Cyclical transmission is activated.

o Set the parameter "Cyclical transmission of feedback telegram?" on parameter page "Kx Feedbacks" (x = number of dimming channel 1...4) to "No".Cyclical transmission is deactivated so that the feedback telegram is transmitted to the busonly when updated by the actuator.

i The cycle time is defined centrally for all dimming channels on the parameter page "Times".i During an active delay after bus voltage return no feedback telegram will be transmitted

even if a switching state changes.

Activate brightness value feedbackThe brightness value feedback can be used as an active message object or as a passive statusobject. As an active message object, the brightness value feedback information is also directlytransmitted to the bus for each update of the feedback value. As a passive status object, thereis no telegram transmission after an update. In this case, the object value must be read out. TheETS automatically sets the object communication flags required for proper functioning.The parameter "Feedback brightness value ?" can be preset separately for each dimmingchannel under "Kx - "feedbacks" (x = number of the dimming channel 1...4).The feedbacks must be enabled on parameter page "Kx - Enabled functions".o Set the parameter to "feedback object is active signalling object".

The "brightness value feedback" object is enabled. The brightness value is transmittedonce this is updated. An automatic telegram transmission of the feedback takes place afterbus/mains voltage return or after programming with the ETS.

o Set the parameter "Feedback object is passive status object".The "brightness value feedback" object is enabled. The brightness value will be transmittedin response only if the feedback object is read out from by the bus. No automatic telegramtransmission of the feedback takes place after bus voltage return or after programming withthe ETS.

o Set the parameter to "no reaction".The brightness value feedback is deactivated.

i A feedback of the current brightness value via the "brightness value" object – even if a Ü-Flag is set – is not possible.

Presetting update of the brightness value feedbackIn the ETS you can specify when the actuator should update the feedback value for thebrightness value in case of an actively transmitting communication object. The object valueupdated by the actuator is then signalled actively to the bus.

Page 73 of 157



The parameter "Upgrade of the object value for feedback of brightness value" can be presetseparately for each dimming channel on the parameter page "Kx - "feedbacks" (x = number ofthe dimming channel 1...4).The feedbacks must be enabled on parameter page "Kx - Enabled functions". In addition, thebrightness value feedback must either be configured to actively transmitting or passivelyreadable.o Set the parameter to "after each update obj. brightness feedback".

The actuator updates the feedback value in the object once a new telegram is received onthe input object "brightness feedback". With an actively transmitting feedback object, a newtelegram is also then actively transmitted to the bus each time. The telegram value of thefeedback does not necessarily have to change in the process. Hence, a correspondingbrightness value feedback is also generated on the "brightness value feedback" objectsuch as in the case of cyclical telegrams for example.

o Set the parameter to "only if the feedback value changes".The actuator only updates the feedback value in the object if the telegram value(e.g. "0 %" to "100 %") also changes. If the telegram value of the feedback does notchange (e.g. in the case of cyclical telegrams to the "brightness value" object with the sametelegram value), the feedback then remains unchanged. Consequently, with an activelytransmitting feedback object, no telegram with the same content will be transmittedrepeatedly either.This setting is recommendable, for instance, if the "brightness value" and "brightness valuefeedback" objects are linked to an identical group address. This is often the case whenactivating by means of light scene push-button sensors (recall and storage function).

Activating brightness value feedback on return of bus voltage or after programming withthe ETSIf used as active message object, the brightness value feedback information is transmitted tothe bus after bus voltage return or after programming with the ETS. In these cases, thefeedback telegram can be time-delayed with the delay being preset globally for all dimmingchannels together (see page 52).o Set the parameter "Time delay for feedback after bus voltage return ?" on parameter page

"Kx Feedbacks" (x = number of dimming channel 1...4) to "Yes".The brightness value feedback will be transmitted with a delay after bus voltage return orafter programming with the ETS. No feedback telegram is transmitted during a runningdelay, even if the brightness value changes during this delay.

o Set the parameter "Time delay for feedback after bus voltage return ?" on parameter page"Kx Feedbacks" (x = number of dimming channel 1...4) to "No".The brightness value feedback will be transmitted immediately after bus voltage return orafter programming with the ETS.

i After programming with the ETS, the brightness value feedback is always transmitted witha basic delay of a few seconds (initialisation procedure of the actuator / possibly calibrationof the load types). The basic delay is added to the "Delay after bus voltage return"configured in the ETS, if activated.

Presetting the cyclical transmission function for the brightness value feedback telegramThe brightness value feedback telegram can also be transmitted cyclically via the activemessage object in addition to the transmission after updating.o Set the parameter "Cyclical transmission of feedback telegram?" on parameter page "Kx

Feedbacks" (x = number of dimming channel 1...4) to "Yes".

Page 74 of 157



Cyclical transmission is activated.o Set the parameter "Cyclical transmission of feedback telegram" on parameter page "Kx

Feedbacks" ( x = number of the dimming channel 1...4) to "No".Cyclical transmission is deactivated so that the feedback telegram is transmitted to the busonly when updated by the actuator.

i The cycle time is defined centrally for all dimming channels on the parameter page "Times".i During an active delay after bus voltage return no feedback telegram will be transmitted

even if a brightness value changes.

4.2.4.2.8 Timing functionsUp to two time functions can be preset for each dimming channel independent of each other.The time functions affect the communication objects "switching" or "central switching" only (if acentral function is activated for the channel concerned) and delay the object value receiveddepending on the telegram polarity (Figure 16).

Figure 16: Function diagram of the timing functions

i In the "speed controller" operating mode for the "1-gang" device variant - similar to thedescription of the brightness values for lighting control in this chapter - speed values can beconfigured in the ETS. The differences between the "speed controller" operating modecompared to the "lighting control" operating mode can be read in detail in the chapter"Features in the speed controller operating mode" (see page 118).

activating switch-on delayThe switch-on delay can be activated separately in the ETS for each dimming channel.The timing functions must be enabled on parameter page "Kx - Enabled functions".o On parameter page "Kx – Time delays" (x = Number of the dimming channel 1...4), preset

the parameter "Selection of time delay" to "Switch-on delay" or to "switch-on delay andswitch-off delay". The desired switch-on delay time can be configured.

Page 76 of 157



The switch-on delay is enabled. After reception of an ON telegram via the "switching"object, the configurable time is started. Another ON-telegram triggers the time only whenthe parameter "Switch-on delay retriggerable ?" is set to "Yes". An OFF-telegram receivedduring the ON-delay will end the delay and sets the switching status to "OFF".

Activate switch-off delayThe switch-off delay can be activated separately in the ETS for each dimming channel.The timing functions must be enabled on parameter page "Kx - Enabled functions".o On parameter page "Kx – Time delays" (x = Number of the dimming channel 1...4), preset

the parameter "Selection of time delay" to "Switch-off delay" or to "Switch-on delay andswitch-off delay". Configure the desired switch-off delay.The switch-off delay is enabled. After reception of an OFF-telegram via the "switching"object, the configurable time is started. Another OFF-telegram triggers the time only whenthe parameter "switch-off delay retriggerable ?" is set to "Yes". An ON-telegram receivedduring the OFF-delay will end the delay and sets the switching status to "ON".

i Feedback: If a time delay has been preset and if the switching state is changed via the"Switching" object, the time delay must have elapsed before feedback telegrams will betransmitted.

i At the end of a disabling function or forced position function, the brightness state receivedduring the function or adjusted before the function can be tracked. Residual times of timefunctions are also tracked if these had not yet fully elapsed at the time of the reactivation orforced control.

i The time delays do not influence the staircase function if this is enabled.i A time delay still in progress will be fully aborted by a reset of the actuator (bus/ mains

voltage failure or ETS programming).

Page 77 of 157



4.2.4.2.9 Soft ON/OFF functionThe soft-functions permit a dimming channel to be switched on or off at reduced speed when aswitching command is received via the "Switching" or "Central switching" communicationobjects.If the soft ON function is activated, a dimming procedure is executed until the switch-onbrightness when switching on. This also occurs if the dimming channel is already switched on toa brightness value smaller than switch-on brightness. Likewise, with the soft OFF function, adimming procedure is executed to 0 % brightness after receipt of an OFF telegram (Figure 17).The dimming speeds can be configured separately in the ETS for the soft ON and soft OFFfunction. The relative dimming increment time between 2 of 255 dimming increments isconfigured directly.The soft ON or soft OFF functions are not retriggerable by the receipt of further switchingtelegrams while maintaining the switching status. The soft functions can be activated andconfigured separately in the ETS.

Figure 17: Dimming behaviour of the soft ON/OFF functions (as an example)

i The soft ON function cannot be configured in the "speed controller" operating mode for the"1-gang" device variant. Additional differences between the "speed controller" operatingmode compared to the "lighting control" operating mode can be read in detail in the chapter"Features in the speed controller operating mode" (see page 118).

The soft functions also have effects on the switching edges of the staircase function (Figure 18).

Page 78 of 157



Figure 18: The function diagram of the soft functions

i A dimming channel disabled via the bus can also flash for the disabling function dependingon the ETS configuration. Dimming is not executed with the soft functions during ON andOFF flashing.

Enabling and setting soft ON functionThe soft ON function can be set separately for each dimming channel in the ETS.The switch-on/switch-off behaviour on the parameter page "Kx Enabled functions" (x = numberof dimming channel 1...4) must be enabled.o Set the parameter "Soft ON function ?" on the parameter page "Kx – Switch-on/switch-off

behaviour" to "Yes".The soft ON function is enabled. The parameter for the dimming increment time (timebetween 2 of 255 dimming increments) of the soft ON function becomes visible.

o Configure the parameter "Time for dimming increment soft ON" to the required dimmingincrement time.

Enabling and setting soft OFF functionThe soft OFF function can be set separately for each dimming channel in the ETS.The switch-on/switch-off behaviour on the parameter page "Kx Enabled functions" (x = numberof dimming channel 1...4) must be enabled.

Page 79 of 157



o Set the parameter "Soft OFF function ?" on the parameter page "Kx – Switch-on/switch-offbehaviour" to "Yes".The soft OFF function is enabled. The parameter for the dimming increment time (timebetween 2 of 255 dimming increments) of the soft OFF function becomes visible.

o Configure the parameter "Time for dimming increment soft OFF" to the required dimmingincrement time.

Page 80 of 157



4.2.4.2.10 Automatic switch-offThe switch-off function permits automatic switching of a dimming channel after a brightnessvalue was dimmed or jumped to and this new brightness value is below a switch-off brightnessset in the ETS. A time delay can be configured optionally up to switching off (cf. Fig. 10).The switch-off function is activated after reaching a constant brightness value, i.e. after acompleted dimming procedure.The automatic switch-off function, for example, not only makes it possible to set the lighting tobasic brightness but to switch off as well by means of relative dimming. A further application istime-controlled 'Good night switch-off' of a dimmed children's room lighting or the automaticswitching off of a fan at very low speed (in the "speed controller" operating mode).i In the "speed controller" operating mode for the "1-gang" device variant - similar to the

description of the brightness values for lighting control in this chapter - the speed valuescan be configured in the ETS.

Figure 19: Dimming and switching behaviour of the automatic switch-off function

i Switching off always takes place without soft OFF function, i.e. jumping.i The switch-off brightness in the dimmable brightness range can be set between basic and

maximum brightness or minimum and maximum brightness. The switch-off function isalways active if the switch-off brightness is configured to maximum brightness and themaximum brightness is randomly undershot.

i The feedback objects for switching state and brightness value are updated by theautomatic switch-off function after switching off.

The automatic switch-off can firstly be activated by a dimming procedure initiated via the 4-bit("dimming") or 1-byte ("brightness value") communication object. Secondly, the automaticswitch-off can also be activated if a dimming channel is switched on (switch-on brightness <switch off brightness) or a brightness is set by programming with the ETS or by a bus voltagefailure or by bus / mains voltage return. The automatic switch-on can also be activated during a

Page 81 of 157



scene recall.It should be noted that the disabling function or forced position function overrides the switch-offfunction (Figure 20). If the switch-off function is overridden, the actuator terminates theevaluation of the switch-off brightness.

Figure 20: Function diagram of the automatic switch-off function

Enabling automatic switch-off functionThe automatic switch-off function can be set separately for each dimming channel in the ETS.The switch-on/switch-off behaviour on the parameter page "Kx Enabled functions" (x = numberof dimming channel 1...4) must be enabled.o Set the parameter "Automatic switch-off when undershooting a brightness ?" on the

parameter page "Kx – Switch-on/switch-off behaviour" to "Yes".The automatic switch-off function is enabled and activated. Additional parameters becomevisible.

Setting the switch-off brightnessThe switch-off brightness must be defined for the switch-off function. The switch-off function isset separately for each dimming channel in the ETS.The switch-off function must be enabled in the ETS.o Set the parameter "Switch off if brightness value is smaller" on parameter page "Kx –

Switch-on/switch-off behaviour" to the required brightness value.

Page 82 of 157



Once a dimming procedure causes a value to fall below the parameterized shutoffbrightness and once the brightness has been set to constant, the dimming channelconcerned switches off or alternatively starts the delay until switching off.

i It should be noted that the configured value for the switch-off brightness is greater than anyconfigured minimum brightness and less than the set maximum brightness (minimumbrightness < switch-off brightness < maximum brightness)!

i Using the staircase function with pre-warning/continuous lighting: The reduced brightnessof the pre-warning or continuous lighting does not start the switch-off function afterreaching or undershooting the switch-off brightness!

Setting the delay of the switch-off functionA delay can be activated before the switch-off function switches-off automatically afterundershooting the switch-off brightness at the end of a dimming procedure. The time for thedelay can optionally be enabled separately for each dimming channel.The switch-off function must be enabled in the ETS.o Configure the parameter "Delay until switching off" on the parameter page "Kx – Switch-on-

/Switch-off behaviour" to the required delay time.Once a dimming procedure causes a value to fall below the parameterized shutoffbrightness and once the brightness has been set to constant, the actuator triggers thedelay time. The dimming channel concerned switches off for good once the delay time haselapsed. The delay time can be re-triggered by further dimming procedures.

i For the "1-gang" device variant in the "speed controller" operating mode it should be notedthat the delay time of the switch-off function is set greater than the "dwell time in cutting-inspeed" (parameter page "K1 - General")! Otherwise, after the dwell time elapsesimmediately after switching off a motor, the switch-on function will have no effect becausethe dwelling in the cutting-in speed has a higher priority.

4.2.4.2.11 Staircase function / Time dimmer functionThe staircase function can be used for implementing time-controlled lighting of a staircase or forfunction-related applications. The staircase function must be enabled in the ETS on parameterpage "Kx - Enabling functions (x = Number of the dimming channel 1...4) in order for therequired communication objects and parameters to be visible.The staircase function is activated via the communication object "staircase function start / stop"and is independent of the "switching" object of a dimming channel (Figure 21). In this way,'parallel operation' of time and normal control is possible, whereby the command last received isalways executed: A telegram to the "switching" object or a scene recall at the time of an activestaircase function aborts the staircase time prematurely and presets the switching stateaccording to the received object value (the time delays are also taken into account) or scenevalue. Likewise, the switching state of the "switching" object can be overridden by a staircasefunction.Time-independent continuous light switching can also be implemented in combination with adisabling function because the disabling function has a higher priority and overrides theswitching state of the staircase function.The staircase function can also be extended by means of a supplementary function. At thesame time, it is possible activate a time extension. The "time extension" permits retriggering ofan activated staircase via the object "Staircase function Start / Stop" n times. Alternatively, the"Time preset via the bus" can be set. With this supplementary function, the configured staircasetime can be multiplied by a factor received via the bus, thus it can be adapted dynamically.Furthermore, an extension of the staircase function can be implemented by means of aseparate switch-on delay and pre-warning function. During the pre-warning, the brightness of adimming channel can be reduced. According to DIN 18015-2, the pre-warning should warnpersons on the staircase that the light will soon be switched off. As an alternative to the pre-warning at the end of the staircase time, the actuator can activate reduced continuous lighting.In this way, for example, long, dark hallways can have permanent basic lighting.

Figure 21: Function diagram of the staircase function

Page 84 of 157



i In the "speed controller" operating mode for the "1-gang" device variant the staircasefunction is described as a time dimmer function. The supplementary function "timeextension" is not necessary in the time dimmer function. Additional differences between the"speed controller" operating mode compared to the "lighting control" operating mode canbe read in detail in the chapter "Features in the speed controller operating mode" (seepage 118).

Specifying switch-on behaviour of the staircase functionAn ON telegram to the "staircase function start/stop" object activates the staircase time (TEIN),the duration of which is defined by the "staircase time" parameters. The output switches toswitch-on brightness.At the end of the staircase time, the dimming channel shows the "reaction at the end of thestaircase time" configured in the ETS. At the same time, the channel can switch off, optionallyactivate the pre-warning time (TVorwarn) of the pre-warning function (see page 88-89) or dim tothe reduced continuous lighting (application: e.g. long, dark hallways). Taking into account anypossible pre-warning function, this gives rise to the example switch-on behaviour of thestaircase function (Figure 22).

Figure 22: Switch-on behaviour of the staircase function without soft functions

In addition, switching on can be influenced by the soft functions of the actuator. Taking intoaccount any soft ON and soft OFF function, this gives rise to a modified switch-on behaviour ofthe staircase function (Figure 23).

Page 85 of 157



Figure 23: Switch-on behaviour of the staircase function with soft functions(for example with minimum brightness = 0 %)

o Set the parameter "Staircase function ?" on parameter page "Kx Enabled functions" (x =number of dimming channel 1...4) to "enabled".The staircase function is enabled. Additional parameters become visible on the parameterpage "Kx – Staircase function".

o In the "staircase time" parameter on parameter page "Kx – Staircase function", configurethe necessary switch-on time of the staircase function.

o Set the parameter "Staircase time retriggerable ?" on the parameter page "Staircasefunction" to "Yes".Every ON telegram received during the ON phase of the staircase time retriggers thestaircase time completely.

o The parameter "Staircase time retriggerable ?" is alternatively preset to "no".ON telegrams received during the ON phase of the staircase time are rejected. Thestaircase time is not retriggered.

i An ON telegram received during the pre-warning time or during the reduced continuouslighting triggers the staircase time independently of the parameter "Staircase timeretriggerable ?" always afterwards.

Specifying switch-off behaviour of the staircase functionIn the case of a staircase function, the reaction to an OFF telegram can also be configured onthe object "staircase function start/stop". At the end of the staircase time, a dimming channelalways shows the "reaction at the end of the staircase time" configured in the ETS, without thereceipt of an OFF telegram. At the same time, the channel can switch off, optionally activate thepre-warning time (TVorwarn) of the pre-warning function (see page 88-89) or dim to the reducedcontinuous lighting (application: e.g. long, dark hallways).If, on the other hand, the dimming channel receives an OFF telegram via the object "Staircasefunction start/stop", the actuator evaluates the parameter "Reaction to an OFF-telegram". In thiscase, the channel can react immediately to the OFF telegram and end the staircase timeprematurely. Alternatively, the OFF telegram can be ignored.Taking into account any possible pre-warning function, this gives rise to the example switch-offbehaviour of the staircase function (Figure 24).

Page 86 of 157



Figure 24: Switch-off behaviour of the staircase function without soft functions

In addition, the switch-off can be influenced by the soft functions of the actuator. Taking intoaccount any soft ON and soft OFF function, this gives rise to a modified switch-off behaviour ofthe staircase function (Figure 25).

Figure 25: Switch-off behaviour of the staircase function with soft functions(for example with minimum brightness = 0 %)

The parameter "Reaction to OFF-telegram" on the parameter page "Kx – Staircase function" (x= number of the dimming channel 1...4), defines whether the staircase time (TEIN) of thestaircase function can be aborted prematurely.The staircase function must be enabled in the ETS.o Set the parameter "Reaction to OFF-telegram" to "switch off".

Once an OFF telegram is received via the object "Staircase function start/stop" during theON phase of the staircase time, the dimming channel concerned switches off immediately.If the staircase time is stopped prematurely by such a telegram, there is no pre-warning, i.e.the pre-warning time is not started. It is also not dimmed to a reduced continuous lighting.It is also possible to switch off prematurely during a dimming procedure of a soft function orduring a pre-warning or reduced continuous lighting.

o Set the parameter "Reaction to OFF-telegram" to ignore".

Page 87 of 157



OFF telegrams received via the object "staircase function start / stop" during the ON phaseof the staircase function are rejected. The staircase time will be executed completely to theend with the configured "behaviour at the end of the staircase time".

Setting the pre-warning function of the staircase functionAt the end of the switch-on time of the staircase function, the actuator for the dimming channelconcerned shows the "reaction at the end of the staircase time" configured in the ETS. Thechannel can be set to switch off immediately, alternatively to dim to the reduced continuouslighting (application: e.g. long, dark hallways) or to execute the pre-warning function. If theparameter is configured to "activate pre-warning time", the pre-warning time (TVorwarn) and pre-warning brightness can be configured in the ETS.The pre-warning should, according to DIN 18015-2, warn persons still on the staircase that thelight will soon be switched off. As a pre-warning, a dimming channel can be set to a pre-warningbrightness before the channel switches off permanently. The pre-warning brightness is normallyreduced in the brightness value compared to the switch-on brightness.The pre-warning time is added to the staircase time (TEIN) (Figure 26). The pre-warning timeinfluences the values of the feedback objects so that the switching state "OFF" and the value "0"is first tracked after the pre-warning time in the feedback objects has elapsed.

Figure 26: The pre-warning function of the staircase function without soft OFF function

Additionally, the pre-warning function can also be extended by the soft OFF function. Takinginto account any soft OFF function, this gives rise to a modified switch-off behaviour of thestaircase function after the pre-warning has elapsed (Figure 27).

Page 88 of 157



Figure 27: The pre-warning function of the staircase function with soft OFF function(for example with minimum brightness = 0 %)

i The pre-warning brightness does not necessarily have to be less than the switch-onbrightness. The pre-warning brightness can always be configured to values betweenbasic/minimum brightness and maximum brightness.

The staircase function must be enabled.o Set the parameter "Reaction at the end of the staircase time" on the parameter page "Kx –

Staircase function" (x = number of the dimming channel 1...4) to "activate pre-warningtime".The pre-warning function is enabled. The desired pre-warning time (TVorwarn) can be preset.

o Configure the "pre-warning time".o Set the parameter "Reduced brightness during the pre-warning time (1...100 %)" to the

desired brightness value.During the pre-warning time, the dimming channel is set to the configured brightness value.

i The configured value for the reduced brightness must be greater than or equal to theminimum brightness (if configured) or less than or equal to the maximum brightness!

i An ON telegram to the object "Staircase function start/stop" while a pre-warning function isstill in progress stops the pre-warning time and always starts (independently of theparameter "Staircase time retriggerable ?") the staircase time anew. Even during the pre-warning time, the parameter "reaction to OFF telegram" is evaluated so that a pre-warningin progress can be terminated early by switching off.

i Using the automatic switch-off function: The reduced brightness of the pre-warning doesnot start the switch-off function after reaching or undershooting the switch-off brightness!

Setting continuous lighting of the staircase functionAt the end of the switch-on time of the staircase function, the actuator for the dimming channelconcerned shows the "reaction at the end of the staircase time" configured in the ETS. Thechannel can be set to switch off immediately, alternatively to execute a pre-warning function, orto dim to reduced continuous lighting. The reduction of the lighting to continuous lighting afterthe staircase time has elapsed is appropriate, for example, if a certain degree of artificial lightshould be switched on permanently in long, dark hallways. Switching to switch-on brightness byactivating the staircase function normally takes place by additional presence detectors or motiondetectors when people are present in the hallway.If the parameter "Reaction at the end of the staircase time" is configured to "activate reduced

Page 89 of 157



continuous lighting", the brightness for the continuous lighting can be configured in the ETS.The continuous brightness is normally reduced in the brightness value compared to the switch-on brightness.The continuous lighting remains permanently active after the staircase time has elapsed. Onlywhen an ON telegram is received again via the object "Staircase function start/stop" does theactuator switch back to the switch-on brightness and start counting the staircase time again.The receipt of an OFF telegram via the object "staircase function start/stop" only switches thecontinuous lighting off if the parameter "Reaction to OFF-telegram" is configured to "switch off".i A dimming channel can always be switched on and off via the "switching" object

independently of the staircase function. Consequently, continuous lighting will also beoverridden if telegrams arrive on the actuator via the "switching" object.If permanent continuous lighting is desired, which cannot be influenced by the "switching"object nor by the object of the staircase function, the disabling function of the actuatorshould be used.

Figure 28: The continuous lighting of the staircase function without soft functions

Additionally, the continuous lighting can also be extended by the soft function. Taking intoaccount any soft ON and soft function, this gives rise to modified continuous lighting behaviourof the staircase function (Figure 27).

Page 90 of 157



Figure 29: The continuous lighting of the staircase function with soft OFF functions

i The brightness of the continuous lighting does not necessarily have to be less than theswitch-on brightness. The brightness of the continuous lighting can always be configured tovalues between basic/minimum brightness and maximum brightness.

The staircase function must be enabled.o Set the parameter "Reaction at the end of the staircase time" on the parameter page "Kx –

Staircase function" (x = number of the dimming channel 1...4) to "activate reducedcontinuous lighting".The continuous lighting is enabled. The "reduced brightness for continuous lighting (1...100%)" can be set to the desired brightness value.

i The configured value for the reduced brightness must be greater than or equal to theminimum brightness (if configured) or less than or equal to the maximum brightness!

i An ON telegram to the object "Staircase function start/stop" always starts (independently ofthe parameter "Staircase time retriggerable ?") the staircase time anew. Even duringactivated continuous lighting, the parameter "Reaction to OFF telegram" is evaluated sothat continuous lighting can be switched off.

i Using the automatic switch-off function: The reduced brightness of the continuous lightingdoes not start the switch-off function after reaching or undershooting the switch-offbrightness!

Setting supplementary function of the staircase function – time extension With the time extension function, the staircase time can be retriggered several times (i.e.extended) via the "Staircase function start/stop" object. The duration of the extension ispredefined by several operations at the control section (several ON telegrams in succession).The configured staircase time can be extended in this way by the configured factor (a maximumof 5-fold). The time is then always extended automatically at the end of a single staircase time(TEIN).

Page 91 of 157



Figure 30: Time extension of the staircase function

With this function, the lighting time in a staircase can be extended (e.g. by a person aftershopping) by a defined length without having to retrigger the lighting every time the lightingshuts off automatically.The staircase function must have been enabled on parameter page "Kx – Enabled functions.o Set the parameter "Supplementary function for staircase function" on the parameter page

"Kx – Staircase function" to "time extension" and set the maximum desired factor on theparameter "maximum time extension".The staircase time is retriggered each time an ON telegram is received on the "staircasetime start/stop" object after the staircase time has elapsed, depending on the number oftelegrams received, but only as often as pre-defined by the configured factor. For example,the "3-fold time" setting means that after the started staircase time has elapsed, it can beretriggered automatically a maximum of three additional times. The time is thereforeextended a maximum of four fold (Figure 30).

i A time extension can be triggered during the entire staircase time (TEIN). There is no timelimit between two telegrams for the time extension. Telegrams for the time extension areonly evaluated during the staircase time. An ON telegram during the pre-warning functionor continuous lighting triggers the staircase time as a restart, which means that a new timeextension is possible.

i If a time extension was configured as a supplementary function, the parameter "Staircasetime retriggerable ?" is preset to "No" because the retriggering takes place by the timeextension.

i The time extension cannot be configured in the "speed controller" operating mode for the"1-gang" device variant.

Setting supplementary function of the staircase function – time preset via the busWith the time preset via the bus, the configured staircase time can be multiplied by an8-bit factor received via the bus, thus it can be adapted dynamically. With this setting, the factoris derived from the object "staircase time factor". The possible factor value for setting thestaircase time is between 1…255.The entire staircase time arises as a product from factor (object value) and the configuredstaircase time as a basis as follows...Staircase time = (staircase time object value) x (staircase time parameter)Example:Object value "staircase time factor" = 5; parameter "staircase value" = 10s.-> set staircase time = 5 x 10s = 50 sAlternatively, the staircase function parameter can define whether the receipt of a new factoralso starts the staircase time of the staircase function at the same time. In this case, the object

Page 92 of 157



"Staircase function start/stop" is not necessary and the received factor value determines thestarting and stopping.The staircase function must have been enabled on parameter page "Kx – Enabled functions.o Set "supplementary function for staircase function" on the parameter page "Kx – Staircase

function" to "time preset via the bus" and set the parameter "staircase function activatablevia 'staircase time' object ?" to "No".The staircase time can be adapted dynamically by the object "staircase time factor". Avalue "0" is interpreted as value "1". The staircase function is started and stoppedexclusively via the "staircase function start / stop" object.

o Set "supplementary function for staircase function" on the parameter page "Kx – Staircasefunction" to "time preset via the bus" and set the parameter "staircase function activatablevia 'staircase time' object ?" to "Yes".The staircase time can be adapted dynamically by the "staircase time factor" object. Inaddition, the staircase function is started with the new staircase time (the "staircasefunction start / stop" is not necessary) after receiving a new factor. A factor value "0" isinterpreted as an OFF telegram, whereby in this case, the configured reaction to an OFFtelegram is evaluated, too.A larger staircase with several floors is an example as an application for the time preset viathe bus with automatic starting of the staircase time. On each floor there is a pushbuttonthat transmits a factor value to the staircase function. The higher the floor, the greater thefactor value transmitted so that the lighting stays switched on longer if the passing throughthe staircase needs more time. When a person enters a staircase and a pushbutton ispressed, the staircase time is now adjusted dynamically to the staircase time and switcheson the lighting at the same time, too.

i Setting "Staircase function activatable via"Staircase time" object ?" = "Yes":A factor > 0 received during a warning time triggers the staircase time independently of theparameter "staircase time retriggerable ?" always afterwards.

i After a reset (bus voltage return or ETS programming) the "staircase time factor" object isalways initialised with "1". The staircase function is not started automatically solely as theresult of this, however (see page 93-94).

i The two supplementary functions "time extension" and "time preset via the bus" can onlybe configured alternatively.

Behaviour of the staircase function after bus or mains voltage return presettingThe staircase function can be started automatically after bus or mains voltage return.The staircase function must have been enabled on parameter page "Kx – Enabled functions.o Set the parameter "Behaviour after bus or mains voltage return" on the parameter page "Kx

– General" to "activate staircase function".i In the "speed controller" operating mode for the "1-gang" device variant, the parameter

setting is called "activate time dimmer function".Immediately after bus or mains voltage return, the staircase time of the staircase function isstarted.

i The parameter "behaviour after bus or mains voltage return" will always be executed onreturn of bus voltage only if the mains voltage (without bus) is switched on. If the mainsvoltage is switched on when the bus voltage is present, the actuator does not execute anyparticular reaction.

i With this setting you should note that the staircase function is also enabled andprogrammed. When the staircase function is not enabled, there is no reaction afterbus/mains voltage return with this setting.

Page 93 of 157



i The configured behaviour will only be executed, if no forced position on bus voltage returnis activated.

4.2.4.2.12 Light scene functionUp to 8 scenes can be programmed and scene values stored separately in the actuator for eachdimming channel. The scene values are recalled or stored via a separate scene extensionobject by means of extension telegrams. The datapoint type of the extension object permitsaddressing a maximum of 64 scenes. This means that, in the configuration of a scene, it ispossible to specify which scene number (1...64) contacts the internal scene (1...8).The scene function must be enabled on parameter page "Kx - Enabling functions" for eachdimming channel in order for the required communication objects and parameters (on theparameter page "Kx - Scenes") to be visible.The scene function can be combined together with other functions of a dimming channel (cf. Fig20), whereby the last received or preset state is always executed:Telegrams to the "switching", "dimming" or "brightness value" objects, a scene recall or scenestorage telegram at the time of an active staircase function aborts the staircase timeprematurely and presets the brightness state according to the received object value (timedelays are also taken into account) or scene value. Likewise, the brightness state of thedimming channel, which was preset by the "switching", "dimming" or "brightness value" objectsor by a scene recall, can be overridden by a staircase function.

Figure 31: Function diagram of the scene function

i In the "speed controller" operating mode for the "1-gang" device variant - similar to thedescription of the brightness values for lighting control in this chapter - the speed valuescan be configured in the ETS. The differences between the "speed controller" operatingmode compared to the "lighting control" operating mode can be read in detail in the chapter"Features in the speed controller operating mode" (see page 118).

Page 95 of 157



Presetting a scene recall delay for the scene functionEach scene recall of an dimming channel can optionally also be delayed. With this feature,dynamic scene sequences can be configured if several scene output channels are combinedwith cyclical scene telegrams.The scene function must be enabled on parameter page "Kx – Enabled functions (x = number ofthe dimming channel 1...4).o Set the parameter "Delay scene recall?" to "Yes".

The delay time is now activated and can be configured separately. The delay onlyinfluences the scene recall of the dimming channel. The delay time is started on arrival of arecall telegram. The corresponding scene will be recalled and the brightness value set onthe dimmer output only after this time has elapsed.

i Each scene recall telegram restarts the delay time and retriggers it. If a new scene recalltelegram is received while a delay is active (scene recall not yet executed), the old (and notyet recalled scene) will be rejected and only the scene last received executed.

i The scene recall delay has no influence on the storage of scene values. A scene storagetelegram within a scene recall delay terminates the delay and thus the scene recall.

Setting behaviour when recalling a sceneIn the scene configuration of a dimming channel, it is possible to define whether the lightintensity instantly jumps or dims to the scene brightness. When dimming, it can also bepredefined whether the dimming procedure should be executed normally by dimmingincrements or by fading. A scene recall can therefore be executed independent of the setdimming behaviour and dimming characteristic of an output.The behaviour during a scene recall can be configured separately for each scene.The scene function must be enabled on parameter page "Kx – Enabled functions (x = number ofthe dimming channel 1...4).o Set the parameter "Behaviour when recalling a scene" on parameter page "Kx – Scenes" to

"jump to brightness value".The scene brightness values are instantly jumped to during a recall.

o Set the parameter "Behaviour when recalling a scene" on parameter page "Kx – Scenes"to "dim to brightness value via dimming increment time". At the same time, define therequired "dimming increment time (0...255 ms)" to dim to the scene brightness value.The scene brightness values of the scene concerned are dimmed to during a recall. Thetime in the parameter selection defines the duration of the dimming procedure between 2 of255 dimming increments.

o Set the parameter "Behaviour when recalling a scene" on parameter page "Kx – Scenes" to"dim to brightness value via fading". At the same time, define the "fading time (0...240 ms)"required to dim to the scene brightness value.The scene brightness values of the scene concerned are dimmed to during a recall. Thedim fading is now activated The time in the parameter selection defines the duration of thedimming procedure required to reach the scene brightness value. The brightness value of adimming channel at which the dimming starts and the configured dimming characteristichave no significance. Thus, the dimming procedure in case of a scene recall alwaysrequires the exact predefined time.

i The parameter setting "dim via fading" is not available in the "speed controller" operatingmode for the "1-gang" device variant.

Presetting the ETS download behaviour for the scene functionDuring storage of a scene, the scene values are stored permanently in the device (seepage 98). To prevent the stored values from being replaced during ETS programming of theapplication or of the parameters by the originally programmed scene brightness values, theactuator can inhibit overwriting of the scene values. As an alternative, the original values can bereloaded into the device during each programming run of the ETS.The scene function must be enabled on parameter page "Kx – Enabled functions (x = number ofthe dimming channel 1...4).o Set the parameter "Overwrite the values stored in the device during ETS download ?" to

"Yes".During each ETS programming of the application or of the parameters, the scene valuesparameterized in the ETS for the dimming channel concerned will be programmed into theactuator. Scene values stored in the device by means of a storage function will beoverwritten, if any.

o Set the parameter "Overwrite the values stored in the device during ETS download ?" to"No".Scene values stored in the device with a storage function will be maintained. If no scenevalues have been stored, the brightness values last programmed in the ETS remain valid.

i When the actuator is put into operation for the first time, this parameter should be set to"yes" so that the dimming channel is initialized with valid scene values.

Presetting scene numbers and scene brightness values for scene functionThe datapoint type of the scene extension object permits addressing of up to 64 scenes max.For this reason, the scene number (1...64) with which the scene is addressed, i.e. recalled orstored, must be determined for each internal scene (1...8) of the dimming channel. Moreover,the brightness value to be set for the dimming output in case of a scene recall must be specifiedas well.The scene function must be enabled on parameter page "Kx – Enabled functions (x = number ofthe dimming channel 1...4).o Set the parameter "Scene x activatable by scene number" (x = number of the scene (1…8))

on parameter page "Kx – Scenes" for each scene to the numbers with which the scenesare to be addressed.A scene can be addressed with the configured scene number. A setting of "0" deactivatesthe corresponding scene so that neither recalling nor storage is possible.

i If the same scene number is parameterized for several scenes, only the scene with thelowest internal scene number (1...8) will be addressed. The other internal scenes will beignored in this case.

o Set the parameter "brightness value for scene x" (x = number of the scene (1…8)) onparameter page "Kx – Scenes" for each scene to the desired brightness valueDuring a scene recall, the parameterized brightness value is recalled and set on thedimming channel.

i The parameterized brightness value is adopted in the actuator during programming withthe ETS only if the parameter "Overwrite values stored in the device during ETS download?" is set to "Yes".

i It should be noted that the configured value for the scene brightness is greater than aconfigured minimum brightness (if applicable) and less than the set maximum brightness!

Page 97 of 157



Presetting the storage behaviour for the scene functionThe scene brightness value preset according to the function diagram can be stored internallyvia the extension object on reception of a scene storage telegram – also during a dimmingprocedure. In this case, the brightness value can be influenced before the storage by allfunctions of the dimming channel provided the individual functions have been enabled (e.g. alsothe disabling function, forced-control position function, manual control, etc.).The scene function must be enabled on parameter page "Kx – Enabled functions (x = number ofthe dimming channel 1...4).o Set the parameter "Storage function for scene x" (x = number of the scene (1…8)) on

parameter page "Kx – Scenes" for each scene to "Yes".The storage function is activated for the scene in question. On reception of a storagetelegram via the "Scene extension" object, the current brightness value will be internallystored.

o Set the parameter "Storage function for scene x" (x = number of the scene (1…8)) onparameter page "Kx – Scenes" for each scene to "No".The storage function is deactivated for the scene in question. A storage telegram receivedvia the "scene extension" object will be rejected.

4.2.4.2.13 Operating hours counterThe operating hours counter determines the switch-on time of a dimming channel. A channel isactively on for the operating hours counter if the brightness value is greater than "0", i.e. whencurrent is flowing to the load.The operating hours counter adds up the determined switch-on time accurately to the minute forswitched-on dimming channels in full hours respectively (Figure 32). The totalled operatinghours are added in a 2-byte counter and stored permanently in the device. The current counterstatus can be transmitted cyclically to the bus by the "value operating hours counter"communication object or when there is a change in an interval value.

Figure 32: Function of the operating hours counter (using the example of an up-counter)

In the as-delivered state, the operating hour values of all dimming channels is "0". If theoperating hours counter is not enabled in the configuration of a dimming channel, no operatinghours will be counted for the channel concerned. Once the operating hours counter is enabled,however, the operating hours will be determined and added up by the ETS immediately aftercommissioning the actuator.If the operating hours counter is subsequently disabled again in the parameters and theactuator is programmed with this disabling function, all operating hours previously counted forthe dimming channel concerned will be deleted. When enabled again, the counter status of theoperating hours counter is always on "0".The operating hours values (full hours) stored in the device will not be lost in case of a busvoltage failure or by ETS programming. Any summed up operating minutes (full hour not yetreached) will be rejected in this case, however.After bus voltage return or after an ETS download, the actuator passively updates the "valueoperating hours counter" communication object in each dimming channel. The object value canbe read out if the read-flag is set. The object value, depending on the configuration for theautomatic transmission, is actively transmitted if necessary to the bus once the parameterizedtransmit delay has elapsed after bus voltage return (see page 102).The operating hours counter detects any operation of the dimming channels by the manualoperation, which means that switching on a channel also activates the counting of operatinghours and the manual switch-off interrupts a counting operation.No operating hours are counted if the mains voltage supply of the individual load outputs is notswitched on.i If the mains voltage is not switched on (bus voltage switched off / building site operation),

summed-up operating hours will not be stored in the event of a mains voltage failure!

Activating the operating hours countero Set the parameter "enabling functions" on parameter page "Kx - Operating hours counter"

to "enabled".

Page 99 of 157



The operating hours counter is activated.

Deactivating the operating hours countero Set the parameter "enabling functions" on parameter page "Kx - Operating hours counter"

to "disabled".The operating hours counter is deactivated.

i Disabling of the operating hours counter and subsequent programming with the ETS resetsthe counter status to "0".

Setting type of counter of the operating hours counterThe operating hours counter can optionally be configured as an up-counter or down-counter.Depending on this type of counter, a limit or start value can be set optionally, whereby, forexample, the operating time of a lamp can be monitored by restricting the counter range.

Up-counter:After activating the operating hours counter by enabling in the ETS or by restarting, theoperating hours are counted starting at "0". A maximum of 65535 hours can be counted, afterthat the counter stops and signals a counter operation via the "Operating hours count. elapsed"object.A limiting value can be set optionally in the ETS or can be predefined via the communicationobject "Op. hours counter limit value". In this case, the counter operation is signalled to the busvia the "Op. hours counter elapsed" object if the limiting value is reached, but the countercontinues counting - if it is not restarted - up to the maximum value 65535 and then stops. Onlya restart initiates a new counting operation.

Down-counter:After enabling the operating hours counter in the ETS, the counter status is on "0" and theactuator signals a counter operation for the dimming channel concerned after the programmingoperation or after bus voltage return via the "Op. hours counter elapsed" object. Only after arestart is the down-counter set to the maximum value 65535 the counting operation started.A start value can be set optionally in the ETS or can be predefined via the communication object"Op. hours counter start value". If a start value is set, the down-counter is initialised with thisvalue instead of the maximum value after a restart. The counter then counts the start valuedownwards by the hour. When the down-counter reaches the value "0", the counter operation issignalled to the bus via the "Op. hours counter elapsed" and the counting is stopped. Only arestart initiates a new counting operation.The operating hours counter must have been enabled on parameter page "Kx – Enabledfunctions (x = number of the dimming channel 1...4).o Set the parameter "Type of counter" on parameter page "Kx - Operating hours counter" to

"up-counter". Set the parameter "Limit value preset ?" to "yes, as parameter" or "yes, asreceived via object" if it is necessary to monitor the limiting value. Otherwise, reset theparameter to "no". In the "yes, as specified in parameter" setting, specify the required limitvalue (1…65535 h).The counter counts the operating hours forwards starting from "0". If the monitoring of thelimiting value is activated, the actuator transmits a "1"-telegram via the object "Operatinghours count. elapsed" for the dimming channel concerned once the predefined limitingvalue is reached. Otherwise, the counter operation is first transmitted when the maximumvalue 65535 is reached.

Page 100 of 157



o Set the parameter "Type of counter" on parameter page "Kx - Operating hours counter" to"down-counter". Set the parameter "start value preset ?" to "yes, as parameter" or "yes, asreceived via object" if a start value preset is necessary. Otherwise, reset the parameter to"no". In the "yes, as specified in parameter" setting, specify the required start value(1…65535 h).The counter counts the operating hours down to "0" after a restart. With a start valuepreset, the start value is counted down, otherwise the counting operation starts at themaximum value 65535. The actuator transmits a "1"-telegram via the object "Operatinghours count. elapsed" for the dimming channel concerned once the value "0" is reached.

i The value of the communication object "Op. hours counter elapsed" is stored permanently.The object is initialised immediately with the value that was saved before bus voltage returnor ETS programming. If an operating hours counter is in this case identified as elapsed, i.e.if the object value is a "1", an additional telegram will be actively transmitted to the bus assoon as the parameterized transmit delay has elapsed after bus voltage return. If thecounter has not yet elapsed (object value "0"), no telegram is transmitted on return ofbus/mains voltage or after an ETS programming operation.

i With a limiting or start value preset via object: The values received via the object are firstvalidly accepted and permanently saved internally after a restart of the operating hourscounter. The object is initialised immediately with the value that was last saved before busvoltage return or ETS programming. The values received will be lost in the case of a busvoltage failure or by an ETS download if no counter restart was executed before. For thisreason, when specifying a new start or limiting value it is advisable to always execute acounter restart afterwards as well.A standard value of 65535 is predefined provided that no limiting value or start value hasbeen received yet via the object. The values received and stored via the object are reset tothe standard value if the operating hours counter is disabled in the parameters of the ETSand a ETS download is being performed.

i With a limiting or start value predefined via object: If the start or limiting value is predefinedwith "0", the actuator will ignore a counter restart to avoid an undesired reset(e.g. in site operation -> hours already counted by manual operation).

i If the counter direction of an operating hours counter is reversed by reconfiguration in theETS, a restart of the counter should always be performed after programming the actuatorso that the counter is reinitialised.

Restarting the operating hours counterThe counter status of the operating hours can be reset at any time by the communication object"Restart operating hours counter". The polarity of the restart telegram is predefined: "1" = restart/ "0" = no reaction.o Characterise the communication object "restart operating hours counter" with "1".

In the up-counter the counter is initialised with the value "0" after a restart and in the down-counter initialised with the start value. If no start value was configured or predefined by theobject, the start value is preset to 65535.During every counter restart, the initialised counter status is transmitted actively to the bus.During every counter restart, the initialised counter status is transmitted actively to the bus.After a restart, the signal of a counter operation is also reset. At the same time, a "0"telegram is transmitted to the bus via the object "Operating hours count. elapsedIn addition, the limiting or start value is initialised.

i If a new limiting or start value was predefined via the communication object, a counterrestart should always be performed afterwards, too. Otherwise, the values received will belost in the case of a bus voltage failure or by an ETS download.

Page 101 of 157



i If a start or limiting value is predefined with "0", there are different behaviours after a restartdepending on the principle of the value definition...Preset as parameter:The counter elapses immediately after a counter restart.Preset via object:A counter restart will be ignored to avoid an undesired reset (e.g. after installation of thedevices with hours already being counted by manual operation). A limiting or start valuegreater than "0" must be predefined in order to perform the restart.

Transmission behaviour of the operating hours counterThe current value of the operating hours counter is always tracked in the communication object"value operating hours counter". After bus voltage return or after an ETS download, the actuatorpassively updates the "Value operating hours counter" communication object in each dimmingchannel. The object value can be read out if the read-flag is set.In addition, the transmission behaviour of this communication object can be set.The operating hours counter must have been enabled on parameter page "Kx – Enabledfunctions (x = number of the dimming channel 1...4).o Set the parameter "Automatic transmission of counting value" on parameter page "Kx -

Operating hours counter" to "after change by interval value". Set the "Counting valueinterval (1…65535 h)" to the desired value.The counter status is transmitted to the bus as soon as it changes by the predefinedcounting value interval. After bus voltage return or after programming in the ETS, the objectvalue is transmitted automatically after "Delay after bus voltage return" has elapsed if thecurrent counter status or a multiple of this corresponds to the counting value interval. Acounter status "0" is always transmitted in this case.

o Set the parameter "Automatic transmission of counting value" on parameter page "Kx -Operating hours counter" to "cyclical".The counter value is transmitted cyclically. The cycle time is defined independent of thechannel on the parameter page "Times". After bus voltage return or ETS programming, thecounter status is transmitted to the bus after the configured cycle time has elapsed.

4.2.4.2.14 Supplementary functionSupplementary functions can be enabled for each dimming channel. As a supplementaryfunction, a disabling or alternatively a forced position function can be configured. In this respect,only one of these functions can be enabled for one channel. Additionally, a logic operationfunction can be parameterized.The supplementary functions are enabled on parameter page "Kx – Supplementary functions "(x = number of dimming channels 1...4).i In the "speed controller" operating mode for the "1-gang" device variant - similar to the


Setting disabling function as supplementary functionDuring an active disabling function, the KNX bus control of the dimming function concerned isoverridden and locked (Figure 33). Continuous light switching, for example, can also beoverridden.

Figure 33: Function diagram of the disabling function

o On the parameter page "Kx - supplementary functions", set the parameter "type ofsupplementary function" to "disabling function".The disabling function is enabled. The communication object "Disable" and the parametersof the disabling function become visible.

Page 103 of 157



o On the parameter page "Kx - supplementary functions", set the parameter "polaritydisabling object" to the desired polarity.

o Set the parameter "Behaviour at the beginning of the disabling function" to the requiredbehaviour.At the beginning of the disabling function, the configured behaviour will be executed andthe bus control of the dimming channel locked. In the "no reaction" setting, the dimmingchannel shows no response and remains in the brightness state last selected.In the "flashing" setting, the dimming channel is switched on and off cyclically during thedisabling. The "time for flashing" is generally configured for all channels on the parameterpage "General". During flashing, the logical switching state of the dimming channel issignalled back as "switched on 1" and the brightness value as "switch-on brightness". Asoft ON/OFF function is not executed during flashing.In the "Memory value" setting, the active and internally saved brightness value prior toswitching off last time is set (via the "switching" or "central switching" object). Afterprogramming with the ETS, the value is predefined to maximum brightness. Only a busvoltage failure, however, does not delete the memory value.

i The "flashing" setting is not configurable in the "speed controller" operating mode for the"1-gang" device variant.

o Set the parameter "setting the behaviour at the end of the disabling function" to therequired behaviour.At the end of the disabling function, the configured behaviour will be executed and the buscontrol of the dimming channel enabled again. In the "No reaction" setting ,the dimmingchannel shows no response and remains in the state last selected by the disabling functionIn "tracked brightness value", the set state received during the disabling function oradjusted before the disabling function can be tracked at the end of the disabling with theappropriate brightness. Any time functions that are still in progress will also be taken intoaccount if necessary.In the "flashing" setting, the output is switched on and off cyclically after the disabling. Theflashing time is configured generally for all dimming channels on the parameter page"General". During flashing, the logical switching state of the channel is fed back as"switched on 1" and the brightness value as "switch-on brightness". A soft ON/OFF functionis not executed during flashing. The flashing status remains active until another buscommand is received and thereby predefines another brightness status.In the "Memory value" setting, the active and internally saved brightness value prior toswitching off last time is set (via the "switching" or "central switching" object). Afterprogramming with the ETS, the value is predefined to maximum brightness. Only a busvoltage failure, however, does not delete the memory value.

i The "flashing" setting is not configurable in the "speed controller" operating mode for the"1-gang" device variant.

i If, at the start or end of the disabling function a brightness value is configured, the selectedvalue must not undershoot the set minimum brightness or exceed the maximum brightnessin the ETS!

i After a bus failure or after programming the application or the parameters with the ETS, thedisabling function is always deactivated (object value "0"). With the inverted setting "1 =enabled; 0 = disabled", a telegram update "0" must first be carried out after the initialisationuntil the disabling is activated.

i Updates of the disabling object from "activated" to "deactivated do not produce a reaction.i A dimming channel disabled via the KNX can be still be operated manually! At the end of a

manual operation, the actuator executes the disabling reaction for the channel concernedonce again if the disabling function is still activated at this time.

Page 104 of 157



i In the setting "tracked brightness value": During a disabling function, the overriddenfunctions of the actuator (switching, dimming, brightness value, scenes) continue to beexecuted internally. Consequently, newly received bus telegrams are evaluated and timefunctions are triggered as well. At the end of the disabling, the tracked states are set.

Setting forced position function as supplementary functionThe forced position function, according to the function diagram, can also be combined with otherfunctions of a dimming channel (Figure 34). With an active forced position the upstreamfunctions are overridden so that the output concerned is locked.The forced position function possesses a separate 2-bit communication object. The first bit (Bit0) of the object "Forced position" indicates whether the dimming channel is switched off orswitched on by force. If the dimming channel is switched on by force, an ETS parameter defineswhich brightness value it should be switched on to. The second bit (bit 1) activates ordeactivates the forced-position state (see table below).The behaviour of a dimming channel at the end of the forced-position function can beconfigured. In addition, the forced object can be initialised on bus voltage return.

Bit 1 Bit 0 Function0 x Forced position not active -> normal control

0 x Forced position not active -> normal control

1 0 Forced position active: switch off

1 1 Forced position active: switch on to predefined brightness value

Figure 34: Function diagram of the forced position function

o On the parameter page "Kx - supplementary functions", set the parameter "type ofsupplementary function" to "forced position".The forced position function is enabled. The communication object "forced position" and theparameter of the forced position function become visible.

o On the parameter page "Kx - supplementary functions", configure the parameter "switch onbrightness for forced position 'active'" to the required behaviour that should be executed if aforced control is activated via the communication object.When setting a brightness value, the dimming channel adjusts itself to the set brightnessduring a forced-position state. The forced brightness value selected must not exceed themaximum brightness configured in the ETS.In the "No reaction" setting, the bus control of the dimming channel is locked, but thechannel shows no response and remains in the brightness state last selected.In the "Memory value" setting, the active and internally saved brightness value prior toswitching off last time is set (via the "switching" or "central switching" object). Afterprogramming with the ETS, the value is predefined to maximum brightness. Only a busvoltage failure, however, does not delete the memory value.

o Set the parameter "brightness for forced position end 'inactive'" to the required behaviour.At the end of the forced position, the configured behaviour will be executed and the buscontrol of the dimming channel enabled again. In the "No reaction" setting, the dimmingchannel shows no response and remains in the brightness state last selected by the forcedposition.In "tracked brightness value", the state received during the forced position function or thebrightness value adjusted before the function can be tracked at the end of the forcedposition. Any time functions still in progress will also be taken into account if necessary.

i The "switch off brightness for forced position 'active'" is preset to "switch off".

Page 106 of 157



i Updates of the forced position object from "forced position active" to "forced position active"while maintaining the switching status or from "forced position inactive" to "forced positioninactive" show no reaction.

i A forcibly activated dimming channel via the KNX can be still be operated manually! At theend of a manual operation, the actuator executes the forced reaction for the channelconcerned once again if the forced position is still activated at this time.

i In the setting "tracked brightness value" at the end of the forced position: During a forcedposition, the overridden functions of the actuator (switching, dimming, brightness value,scenes) continue to be executed internally. Consequently, newly received bus telegramsare evaluated and time functions are triggered as well. At the forced end, the tracked statesare set.

i The current state of the object of the forced position function will be stored in case of bus ormains voltage failure.

o Set the parameter "behaviour after bus voltage return" to the required behaviour.After bus voltage return, the configured state is transferred to the "Forced position"communication object. When a forced position is activated, the dimming channel isimmediately activated and interlocked accordingly by forced control after bus voltage returnuntil a forced control takes place via the bus. The parameter "Behaviour after bus or mainsvoltage return" on the parameter page "Kx – General" will, in this case, not be evaluated forthe dimming channel concerned.In the "state before bus voltage failure" setting, the forced position state last selected andinternally stored before bus voltage failure will be tracked after bus voltage return. An ETSprogramming operation deletes the stored state (reaction in that case same as with "noforced position active").If the tracked state corresponds to "no forced position active", the force-independentparameter "Behaviour after bus/mains voltage return" will be executed on return of busvoltage (parameter page "Kx – General"). If the forced position is activated, the dimmingchannel is switched on to the brightness value predefined by the parameter "switch onbrightness for forced position 'active'".

i After programming the application or parameters with the ETS, the forced position functionis always deactivated (object value "0").

Setting logic operation function as supplementary functionA logic function can be parameterized separately for each dimming channel. This functionallows the logic operation of the "switching" object state and an additional logic operation object.The state of the communication object for "switching" can also be evaluated with a time delay ifa switch-on delay or switch-off delay is set.The logic operation function , according to the function diagram, can also be combined withother functions of a dimming channel (Figure 35). A combination with the staircase function(time dimmer function for the "speed controller") is not possible, however.

Page 107 of 157



Figure 35: Function diagram of the logic operation function

The following logic operation types are configurable (Figure 36).

Figure 36: Logic operation types of the logic operation function

i "AND with feedback:"With a logic object = "0", the dimming channel is always "0" (logic AND). In this case, thefeedback signal from the output to the "switching" input will directly reset this input when itis being set. The output of the dimming channel can assume the logical state "1" by a newlyreceived "1" on the input "switching" only when the logic object is = "1".

The object "logic operation" can be installed with a preconfigured value after bus voltage returnor after programming with ETS so that a correct logic operation result can be determinedimmediately and set on the output of the dimming channel during a telegram update on the"switching" object.

Page 108 of 157



o On the parameter page "Kx - supplementary functions", set the parameter "Logic operationfunction" to "Yes". to "Yes".The logic operation function is enabled. The communication object "logic operation" and theparameters of the logic operation function become visible.

o Set the parameter "Type of logic operation function" to the desired logic operation type.o Set the parameters "object value of the logic operation object after bus voltage return" and

"object value of the logic operation object after ETS download" to the required initial states.The "logic operation" object is initialised immediately with the set switching states after busvoltage return or ETS programming of the application program or parameters.

i The logic operation function after a reset of the actuator (bus voltage return orprogramming with the ETS) is first executed when at least one input object of the logicoperation is updated by a telegram from the bus.

i The states or switching states specified at the end of a disabling function or forced positionfunction, which are set after programming in the ETS, in the case of bus voltage failure orafter bus or mains voltage return, override the logic operation function. The configured logicoperation is first re-executed and the result set on the output of the dimming channel whenat least one input state of the logic operation is changed or updated.

i A mains voltage return does not influence the communication objects of the actuator. Theobjects remain on the last set state if the bus voltage was connected interruption free.

4.2.4.2.15 Dimming characteristic, dimming behaviour and dimming speedsA dimming procedure can change the brightness (operating mode "lighting control") or speed(operating mode "speed controller") of the lamps connected to a dimming channel. The limits ofthe brightness/speed range adjustable by a dimming procedure is defined either by the basicbrightness and maximum brightness predefined in the ETS, or alternately, by the combination ofminimum brightness and maximum brightness.i In the "speed controller" operating mode for the "1-gang" device variant - similar to the


A channel can be dimmed by...

- relative dimming:Relative dimming can either be triggered by the 4-bit "dimming" communication objectavailable separately in each dimming channel or by a long button-press of the manualoperation. The data format of the "dimming" object complies with the KNX standard DPT"3.007", which means that the dimming direction and relative dimming increments can bepredefined in the dimming telegram or dimming procedures can also be stopped. In relativedimming by local manual operation on the device, a dimming procedure is executed whilstthe appropriate button is pressed. The dimming process ends when the button is releasedor when the basic/minimum brightness or maximum brightness is reached.

- absolute dimming:Absolute dimming is triggered by specifying a brightness value. This value can bepredefined by the 1-byte "brightness value" communication object from KNX the, which isavailable separately in each dimming channel. In addition, brightness values can also beset by a disabling or forced position function or by the scene function. Absolute dimmingcan also be activated, even in case of bus voltage failure, after bus or mains voltage returnor after programming with the ETS, by predefining brightness values.When predefining a brightness value via the object or by a scene recall, it is possible toconfigure in the ETS whether the value is jumped to directly or alternatively whether it isdimmed to via the configured dimming increment time or by fading. In the case of all otherabsolute dimming functions, the brightness values are always instantly jumped to.

i It is not possible to dim a speed value via "fading" in the "speed controller" operating modefor the "1-gang" device version.

The dimming speed is identical for a relative dimming procedure or for the dimming of anabsolute brightness value (not fading) and can be set in the ETS separately for each dimmingchannel in the characteristic parameters.i Even if brightness values are instantly jumped to, the dimming procedure on connected

lamps always takes a very short time as well as when switching without soft ON or softOFF. This dimming procedure is determined by the system. The brightness value instantlyjumped to will be dimmed with the minimum increment of 1 ms. This time cannot be altered.

Configuring dimming characteristicIn the case of the universal dimmer actuator, the technically dimmable brightness range (basicbrightness ... 100 %) is subdivided into 255 dimming increments (8-bit brightness value: 1...255/ 0 = switched off). In the as-delivered state of the actuator, the dimming increment times, i.e.

Page 110 of 157



the dimming times between 2 of 255 dimming increments, are set to the identical length. Thisresults in a linear characteristic curve over the entire brightness range.The dimmable brightness range is limited at the upper limit by the maximum brightnessconfigured in the ETS. The lower brightness range is either defined by the basic brightness(brightness values "1", "2" and "3" -> "1 %") or alternatively, by the minimum brightness. Thedimming characteristics shown in the following diagrams distinguish these configurations andillustrate the resulting real dimming time of a dimming procedure.i In the application program with version "1.2", the dimmable brightness range can be

adjusted to universal power boosters. The parameter "Operation with universal powerbooster ?" is provided for this purpose. In the "Yes" setting, a residual phase anglenecessary for universal power boosters is set on the dimmer output in the highest dimmingposition (100 % brightness value). The output signal cut-on or cut-off in this waycorresponds approx. to a resulting brightness of 90 % compared to an identicallyconstructed dimmer actuator without a power booster. The dimmer actuator then rescalesthe adjustable brightness range automatically for the corresponding channel so that asetpoint and feedback within a range of 0…100% is still possible (always 255 dimmingincrements in the dimmable brightness range).

Page 111 of 157



Figure 38: Linear characteristic dimming curve as an example with minimum brightness > 0 %and maximum brightness

In some practical applications, a linear dimming characteristic is not optimal. Hence, theactuator in the ETS alternatively permits a user-defined adjustment of the dimming progress. Inthis way, for example, brightness changes can be adjusted to the brightness sensitivity of thehuman eye when dimming by subdividing the brightness range in up to three sections withdifferent dimming increment times.

Figure 40: User-defined dimming characteristic as an example with minimum brightness andmaximum brightness

As an additional option, it is possible to set predefined dimming characteristics for incandescentlamps or for halogen lamps in the characteristic parameterization. In this way, the dimmingprogress can be optimised for the named lamp loads. In this case, the dimming actuator workswith fixed implemented brightness sections and dimming increment times.In the "speed controller" operating mode for the "1-gang" device variant, the load-optimisedcharacteristic settings are available in the ETS.

i An increase of the brightness value in the dimmer actuator causes a time decrease of theresidual phase angle. Likewise, a decrease of the brightness value on the dimmer outputcauses a time decrease of the residual phase angle. The residual phase angle determines,among other things, the dark phase of the connected lamps.

o Set the parameter "characteristic curve" on parameter page "Kx dimming characteristic" (x= number of the dimming channel 1...4) to "linear".A linear dimming characteristic curve is set. A dimming increment time can also beconfigured for the entire brightness range in the ETS.

o Set the parameter "characteristic curve" to "user-defined".A user-defined dimmer characteristic curve is set. Another two limiting values and threedimming increment times can be defined for the definition of three brightness sections.

o Set the parameter "characteristic curve" to "adapted for incandescent lamps".A specially adapted dimming characteristic curve is set for incandescent lamps. It is notnecessary to carry out any further settings for the dimming characteristic.

i This setting is not available in the "speed controller" operating mode for the "1-gang" devicevariant.

Page 114 of 157



o Set the parameter "characteristic curve" to "adapted for halogen lamps".A specially adapted dimming characteristic curve is set for halogen lamps. It is notnecessary to carry out any further settings for the dimming characteristic.

i This setting is not available in the "speed controller" operating mode for the "1-gang" devicevariant.

Setting dimming increment timeThe dimming increment speed is identical for a relative dimming procedure or for the dimming ofan absolute brightness value (not fading) and can be set in the ETS separately for eachdimming channel in the characteristic parameters.The configuration of a dimming increment time is only necessary if the characteristic curve is setto "linear" or to "user-defined".The parameter "characteristic curve" is set to "linear".o Set the parameter "time between two dimming increments " on parameter page "Kx

dimming characteristic" to the necessary dimming increment time.During every relative or absolute dimming procedure, the entire brightness range isdimmed with the configured dimming increment speed.

The parameter "characteristic curve" is set to "user-defined".o First define the brightness limit values. For this purpose, on the parameter page "Kx –

Dimming characteristic" set the parameter "brightness limiting value 1. area / 2. area(1...100 %)" and "brightness limiting value 2. area / 3. area (1...100 %)" to the necessarysection limits. While doing so, take care that the brightness limiting value of area 1. / 2. issmaller than the limiting value of area 2. / 3.! Otherwise, there is the risk of malfunction.The dimmable brightness range is divided into three sections. In the following, the dimmingincrement speeds for these three areas can be set separately.

i In the configuration of the limiting value, care must be taken to ensure that the maximumbrightness is not exceeded, or if necessary, the configured minimum brightness is notundershot.

o The parameters "... time between two dimming increments (1...255 ms)" on parameterpage "Kx dimming characteristic" are set to the necessary dimming increment times foreach of the three areas.The dimming characteristic is defined ready. The lighting is dimmed at the specifieddimming increment speeds for each of the three sections.

i The scene dimming increment speed for the dimming of scene values is defined separatelyin the scene parameters of an output (see page 96).

Setting dimming behaviour for absolute dimmingThe dimming behaviour for the absolute dimming can be set separately in the ETS for eachdimming channel via the "brightness value" or "speed" object.o Set the parameter "dimming behaviour after receipt of a brightness value" on parameter

page "Kx General" (x = number of dimming channel 1...4) to "dim".Once a new brightness value is received, it is set by means of the configured dimmingincrement time (see page 115) based on the predefined dimming characteristic.

o Set the parameter "dimming behaviour after receipt of a brightness value" to "jump to".As soon as a new brightness value is received it will be instantly jumped to.

Page 115 of 157



o Set the parameter "dimming behaviour after receipt of a brightness value" to "fading". Inaddition, on the parameter "Time for brightness value via fading", define the necessaryfading time for dimming the scene brightness value.Newly received brightness values will be dimmed. The dim fading is activated The fadingtime defines the duration of the dimming procedure required to reach the new brightnessvalue. The brightness value of a dimming channel on which the dimming starts and theconfigured dimming characteristic have no significance. The dimming procedure thusalways requires the exact predefined time when specifying a new brightness value.

i The parameter setting "fading" is not available in the "speed controller" operating mode forthe "1-gang" device variant.

i Brightness values can also be set by a disabling or forced position function. Absolutedimming can also be activated, even in case of bus voltage failure, after bus or mainsvoltage return or after programming with the ETS, by specifying brightness values. In thecase of these absolute dimming functions, the brightness values are always instantlyjumped to. During a scene recall, the dimming behaviour can be configured separately(see page 96).

Setting dimming behaviour in OFF state for relative dimming (only for program version"1.2" and device generation "V02")A relative dimming process can be triggered by the 4-bit "dimming" communication objectavailable separately in each dimming channel or by a long button-press of the manualoperation. The data format of the "dimming" object complies with the KNX standard DPT"3.007", which means that the dimming direction and relative dimming increments can bepredefined in the dimming telegram or dimming procedures can also be stopped. A relativedimming process is executed via the object until the configured basic minimum or maximumbrightness of the dimming channel is set, the dimming value reaches the dimming incrementpredefined in the telegram or a stop telegram is received. A relative dimming process allows abrightness value to be changed constantly and always starts from the brightness that is setstationary or dynamically at the time of the incoming dimming telegram.A relative dimming telegram can also switch on a dimming channel if this is in the "OFF" state.In some applications, it may be necessary, however, for a switched off dimming channel toremain off until a relative dimming telegram is received. This is interesting when using lightscenes, for instance:Several dimming channels are set to a defined brightness value via a light scene. Otherchannels are switched off by the scene. Only the brightness of channels not switched off by thescene recall should be changed by dimming up afterwards. Here, it is necessary for dimmingchannels not to react to a relative dimming operation and thus not to switch on.The parameter "Behaviour when OFF by relative dimming" defines whether or not a dimmingchannel in the "OFF" state reacts to a relative dimming telegram. This parameter is onlyavailable in the application program with the version "1.2".o Set the parameter to "Dimming up switches channel ON (Standard)".

The dimming channel always reacts to a relative dimming telegram and executes adimming process. In the "OFF" state, the channel switches on with a "dim up" telegram.

o Set the parameter to "Dimming up is ignored (channel remains OFF)".The dimming channel only reacts to a relative dimming telegram when it is switched on. Inthe "OFF" state, the channel ignores a "dim up" telegram.

i In manual operation on the device, it is possible in the "OFF" state to always switch on andincrease brightness by a long press of the button. The parameter "Behaviour when OFF byrelative dimming" thus has no effect on manual operation.

Page 116 of 157



i The parameter "Behaviour when OFF by relative dimming" is only available in theapplication program with the version "1.2" and is only evaluated by devices that contain theversion designation "V02" on the device label (see page 35). If the application program"1.2" with the setting "Behaviour when OFF by relative dimming = Dimming up is ignored" isused in old devices (no designation or designation "V01"), the actuator does not carry outthe configure behaviour. Old devices always switch on the dimming channel if a relativedimming telegram "Dim up" is received in the OFF state.Application programs with the version "1.1" can be programmed in devices with designation"V02". Even in this case, a relative dimming telegram "Dim up" always causes the dimmingchannel in the OFF state to be switched on.

4.2.4.2.16 Special features of the speed controller operating modeApart from controlling lighting, the universal dimmer actuator 1-gang can be used as a speedcontroller of single-phase electric motors. This operating mode can be preselected in the ETSand has a considerable effect on the parameter configuration and function of the device.In the function as speed controller, some parameters and object texts change because thespeed of a connected motor is controlled in the "speed controller" operating mode instead ofbrightness. The speed (e.g. minimum speed) is configured in the ETS as a percentage value.This value represents the dimming value in percent and is a gauge for the output signal's phaseangle of the actuator.The differences between the "speed controller" operating mode compared to the "lightingcontrol" operating mode will be described in more detail in the following...

Load type:In the "Speed controller" operating mode, the dimming principle is preset to "phase cut-on". Ifthe signalling object for load type is enabled, the actuator for the dimming channel alwaystransmits the load type "inductive".

Cutting-in speed:When changing from the "motor switched off" to "motor switched on" status via switching ordimming commands or after a device reset, the actuator first always sets the cutting-in speed.The cutting-in speed should ensure that the motor starts up optimally (e.g. reliable start-up ofthe fan motor through transfer of a higher torque, and thus a higher fan speed).The dwell time that can be configured in the ETS determines how long the actuator allows thecutting-in speed to be active. The actuator changes to the predefined required speed only afterthe "dwell time in cutting-in speed" has elapsed. This change always occurs rapidly without adimming procedure. If the required speed already corresponds to the cutting-in speed (100 %),there is no change.If the motor should be switched off while the cutting-in speed is set, the actuator interrupts thedwell time and switches off the dimming channel immediately. This occurs rapidly without adimming procedure. As a result, soft OFF functions configured optionally in the ETS will not beexecuted in this case.i Required speed: The required speed results directly from switching commands via

switching telegrams or via the manual operation. The required speed is then the cutting-inspeed (Figure 41). Alternatively, the required speed is specified immediately via telegramsto the speed object or via speed specifications of the scene function or disabling and forcedposition functions (Figure 42).In relative dimming via a 4-bit dimming telegram, the increment of the telegram specifiesthe dimming target and thus the required speed. If a relative dimming command is stoppedvia a stop telegram (e.g. pushbutton is released early), the point in time of the stoptelegram decides which speed should be set as the required speed (Figure 43). If the stoptelegram is received on the actuator during the dwell time of the cutting-in speed, theactuator will take into account the speed that was tracked and dimmed up in thebackground at the time of stopping as the required speed. If, however, the stop telegramarrives at the actuator after the dwell time of the cutting-in speed has elapsed, the actuatorsets the speed predefined by the increment of the dimming telegram as the required speed.The stop telegram is rejected in this special case.Push-buttons in the standard configuration normally transmit dimming increments of 100 %.The stop telegram then decides when a relative dimming procedure is aborted prematurely.If relative dimming is used in the "speed controller" operating mode and a relatively shortdwell time is configured for the cutting-in speed, push-buttons should be reconfigured tosmaller dimming increments with telegram repetition. This has the advantage that stoptelegrams do not have to be transmitted in order to dim intermediate values of the possibledimming area.

Figure 41: Cutting-in speed and required speed for switching commands

Figure 42: Cutting-in speed and required speed for value commands

Figure 43: Cutting-in speed and required speed for relative dimming commands

i For the "1-gang" device variant in the "speed controller" operating mode it should be notedthat the delay time of the switch-off function is set greater (see page 83) than the "dwelltime in cutting-in speed"! Otherwise, after the dwell time elapses immediately afterswitching off a motor, the switch-on function will have no effect because the dwelling in thecutting-in speed has a higher priority.

Unnecessary settings:In the "speed controller" operating mode, some configuration options are not necessary in the

Page 119 of 157



ETS owing to changed technical features of the load. The following parameter settings aremodified as compared to the "lighting control" operating mode...- The maximum speed cannot be adjusted by means of a parameter. It is preset to 100 %.- The load failure message cannot be configured.- In the "dimming behaviour after receipt of a speed value" parameter, the "fading" setting is

not necessary.- In the scene configuration, the "dim speed via fading" setting is not necessary.- In the switch-on/switch-off behaviour, the "soft ON function" is not necessary.- In the disabling function, the "flashing" reaction cannot be configured.- The supplementary function "time extension" is not necessary in the time dimmer function.- In the "linear dimming characteristic curve" the settings "adapted for incandescent lamps"

and "adapted for halogen lamps" are not necessary.

4.2.4.3 Delivery stateIn the state as delivered, the device is passive, i.e. no telegrams are transmitted to the bus. Theconnected loads can, however, be operated by manual operation on the device if the mainsvoltage is on. In the manual control mode, no feedback telegrams are sent to the bus. Otherfunctions of the device are deactivated.The device can be programmed and put into operation via the ETS. The physical address ispreset to 15.15.255

Moreover the device has been configured at the factory with the following characteristics...- Operating mode: lighting control- Channel definition: 4 separate dimming channels- Dimming principle: universal- Time between two dimming increments manual operation: 12 milliseconds- Basic brightness: level 5 (standard halogen)- Maximum brightness: 100 %- Switch-on brightness: 100 %- Behaviour in case of bus voltage failure: no reaction- Behaviour after bus voltage return: last brightness value.- Behaviour on the load outputs after mains voltage return: The device calibrates itself to the

load outputs. This procedure depends on the features of the power supply can last up to 10seconds. The outputs switch off afterwards.

- Operating hours counter: deactivated.- Behaviour at the end of manual control: no change.

The as-delivered state can be restored at any time by loading the application program with theaid of the ETS. The manual operation remains activatable in this case.i When connecting a motor "speed controller" operating mode only for "1-gang" device

variant) or parallel wired dimming outputs (for "4-gang" device variant), after the installation,commissioning using the ETS is essential before switching on the mains voltage (seepage 16-17) so that the as-delivered state is replaced by the necessary parameterconfiguration!

To simplify the configuration, all existingdimming channels can be assigned tothe same parameters in the ETS andthus configured identically. Thisparameter stipulates whether everydimming channel of the device can beconfigured individually or whether allchannels should be configured by thesame parameters.In the "all channels equal" setting, thenumber of parameters in the ETS isreduced. The visible parameters arethen used on all channels automatically.Only the communication objects canthen be configured separately for thechannels. This setting should beselected, for example, if all channelsbehave identically and should only beactivated by different group addresses(e.g. in office blocks or in hotel rooms).In the "each channel individual" setting,all dimming channels of the device canbe configured autonomously.

To increase the channel dimmer outputpower, the "4-gang" device variant inparticular can be wired in parallel byreducing the number of channel outputs.The assignment of parallel to wireddimming outputs to the KNX-controllabledimming channels takes place in theETS. The following parameters definehow many dimming channels should beused. The fewer channels that areconfigured, the more dimming outputscan be assigned to a channel by theparameter "effect".

Use dimming channel1?

YesNo

Define whether the first dimmingchannel should be used. This parameteris also preset to "Yes" because adimming channel is always available.This parameter is only visible in thedevice variant "4-gang".


YesNo

Define whether the second dimmingchannel should be used. If the setting is"Yes", the second dimming channel isavailable. If the setting is "No", thedimming channels 2...4 are not

available. The actuator then works as a1-channel device.This parameter is always preset to "Yes"if the parameter configuration in the ETSis identical (see parameter "Setting thechannel parameters").This parameter is only visible in thedevice variant "4-gang".


YesNo

Define whether the third dimmingchannel should be used. If the setting is"Yes", the third dimming channel isavailable. The actuator then works as a3-channel device at least. If the settingis "No", the dimming channels 3 & 4 arenot available. The actuator then worksas a 2-channel device, if the parameter"use dimming channel 2?" is set to"Yes".This parameter is only visible in thedevice variant "4-gang".


YesNo

Define whether the fourth dimmingchannel should be used. If the setting is"Yes", the fourth dimming channel isavailable. The actuator then works as a4-channel device. If the setting is "No",dimming channel 4 is not available. Theactuator then works as a 1, 2 or3-channel device, depending on how theparameters "use dimming channel 2?"and "use dimming channel 3? are set.This parameter is only visible in thedevice variant "4-gang".

The assignment of the KNX controllabledimming channels to the dimmingoutputs is described in the assignmenttable for the device variant "4-gang",which is stored in the device. Theassignment of dimming channel 1 to theoutputs can only be configured in2-channel and 3-channel operation. Thisthen gives rise to the effect of the otherchannels on the outputs. The "Effect ofchannel 1" parameter defines theassignment and, irrespective of this,specifies the effect of the otherchannels.

i The configuration of the effect hasinfluence on the parallel wiring ofthe 4 dimmer outputs and thus hasinfluence on the load distribution.The effect cannot be configuredwith the device variants "1-gang"and "2-gang". The assignment ofdimming channels to the outputsmust be predefined directly by thechannel number.

Define which outputs the seconddimming channel affects. The outputsassigned here to dimming channel 2 canbe wired in parallel if more than oneoutput was assigned.This parameter presetting depends onthe effect of the first dimming channel.

Effect of channel 3 Output 3 (max. 250 W)Output 4 (max. 250 W)Outputs 3-4 (max. 500 W)

Define which outputs the third dimmingchannel affects. The outputs assignedhere to dimming channel 3 can be wiredin parallel if more than one output wasassigned.This parameter presetting depends onthe effect of the first dimming channel.

Effect of channel 4 Output 4 (max. 250 W) Define which output the fourth dimmingchannel affects.If all 4 dimming channels are used,channel 4 can only affect output 4.

The information on thispage can help the electrician toconnect the electrical load to thedimming outputs and hence toassign it to the KNX-controllabledimming channels when installingthe device.

Behaviour at the end ofpermanent manualcontrol during busoperation

The behaviour of the actuator at the endof permanent manual control dependson this parameter.This parameter is only visible if manualcontrol is enabled during bus operation.

No change All telegrams received during an activepermanent manual control mode fordirect operation (switching, dimming,brightness value, scenes) will berejected. After the end of the permanentmanual control mode, the current stateof all outputs remains unchanged. If,however, a forced position or disablingfunction has been activated before orduring manual operation, the actuatorresets the reaction configured for thisfunction for the dimming channelsconcerned.

h Kx - GeneralOperating mode Apart from controlling lighting, the

actuator "1-gang" device variant can beused as a speed controller of single-phase electric motors. The operatingmode is preselected by this parameterand has a considerable effect on theparameter configuration and function ofthe device.i The operating mode is not

adjustable with the device variants"2-gang" and "4-gang". The lightingoperation is always intended here.

Lighting control In the "Lighting control" function, thedimming principle can be selected in theETS. Lighting systems in phase cut-onor phase cut-off are then activated byswitching or dimming commands andbrightness values.

Speed controller In the function as a "speed controller",the dimming principle is predefined tophase cut-on. Some parameter andobject texts change because in the"speed controller" operating mode thespeed of a connected motor is controlledinstead of brightness. The speed (e.g.minimum speed) is configured in theETS as a percentage value. This valuerepresents the dimming value in percentand is a gauge for the output signal'sphase angle of the actuator.

Type of connected load The dimming principle of the dimmingchannel is specified here.This parameter is preset to "Motor(inductive / phase cut-on)" in the "speedcontroller" operating mode for the"1-gang" device variant).

universal(with calibrationprocedure)

The dimming channel calibrates itselfuniversally to the connected load type.After programming with the ETS, afterbus voltage return (without mainsvoltage), after mains voltage return onthe terminal pair "L N" (without busvoltage) or after switching on the mainsvoltage supply of a load output, theactuator calibrates itself automatically tothe connected load. The calibrationprocedure becomes noticeable duringohmic loads by a brief flicker and lasts

Page 128 of 157



up to 10 seconds depending on thenetwork conditions.

electronic transformer(capacitive / phase cut-off)

The dimming channel is preset to phasecut-off principle. There is no automaticcalibration of the load type. Ohmic loadsor electronic transformers can beconnected to the output.

Conventional transformer(inductive / phase cut-on)

The dimming channel is preset to phasecut-on principle. There is no automaticcalibration of the load type.Conventional transformers can beconnected to the output.

LED (Phase cut-off) The dimming channel is preset to anoptimized phase cut-off principle. Thereis no automatic calibration of the loadtype. HV LED or compact fluorescentlamps designed for this dimmingprinciple can be connected to the output(specifications of the lamp manufacturermust be observed).This parameter setting is only availablein the application program with version"1.2" and only in conjunction with thedevice generation "V02" in function.

Operation with universalpower booster ?

If the output power is increased bymeans of universal power boosters, thecorresponding channel configuration ofthe dimmer actuator must be adaptedhere. The dimmer actuator adapts theoutput signal automatically for usinguniversal power boosters based on thesetting of this parameter.This parameter is only available in theapplication program with version "1.2"and only in conjunction with the devicegeneration "V02" in function.

Yes At least one universal power booster isconnected to the dimming channel. Inthe highest dimming position (100 %brightness value), a residual phaseangle necessary for universal powerboosters is set on the dimmer output.The output signal cut-on or cut-off in this

Page 129 of 157



way corresponds to a resultingbrightness of approx. 90 % compared toan identically constructed dimmeractuator without a power booster. Thedimmer actuator rescales the adjustablebrightness range automatically for thecorresponding channel so that apresetting and feedback within a rangeof 0…100% is still possible.

No No universal power booster isconnected to the dimming channel. Inthe highest dimming position (100 %brightness value), the smallest possibleresidual phase angle is set on thedimmer output. As a result, theconnected lighting is set to themaximum lighting level technicallypossible.

Definition of thebrightness range

with basic brightness

with minimum brightness

The brightness range, adjustable byswitching or dimming procedures, canbe limited by defining a lower and upperbrightness value. The lower brightnessvalue is either defined by the basicbrightness, or alternatively, by theminimum brightness. The upperbrightness value is always characterisedby the maximum brightness. Themaximum brightness adjustable in theETS is never exceeded under anycircumstances in the switched-onoperating state of a dimming channel.Neither when switching on nor whendimming.This parameter defines whether theadjustable brightness range at the lowerlimit will be limited by the basicbrightness or by a minimum brightness.This parameter is visible only in the"lighting control" operating mode.

Basic brightness Level 1Level 2Level 3 (Incandescentlamps)Level 4Level 5 (standardhalogen)Level 6Level 7Level 8

The step value set here is a gauge forthe minimum adjustable residual phaseangle of the output signal and is set tothe decimal brightness values "1", "2"and "3". The step value cannot beundershot in any switched-on operatingstate of the dimming channel.This parameter is visible only if the"definition of the brightness range"includes the "basic brightness" and the"lighting control" operating mode is alsopredefined.

Minimum brightness

The brightness set here is not undershotin any switched-on operating state.This parameter is visible only if the"definition of the brightness range"includes the "minimum brightness" andthe "lighting control" operating mode isalso predefined.

Minimum speed 1 % (decimal 3)5 % (decimal 13)10 % (decimal 26)15 % (decimal 38)20 % (decimal 51)25 % (decimal 64)30 % (decimal 77)35 % (decimal 89)40 % (decimal 102)45 % (decimal 115)

The speed set here is not undershot inany switched-on operating state. Duringthe initial commissioning, the devicemust be adapted to the minimum speedof the connected motor by thisparameter.This parameter is visible only if the"speed controller" operating mode ispredefined.

Maximum brightness Basic brightness5 %10 %15 %...95 %100 %

The brightness set here is not undershotin any switched-on operating state. Theselection of the adjustable value isdownwardly limited to 50 % when usinga minimum brightness. Smaller valuescannot be configured in this casebecause otherwise the adjustment rangeof the minimum brightness will be cut(minimum brightness < maximumbrightness).This parameter is visible only in the"lighting control" operating mode. In the"speed controller" operating mode themaximum speed is unalterablypreselected to 100 %.

Cutting-in speed 100 % The parameter is only visible in the"speed controller" operating mode forthe "1-gang" device variant.When changing from the "motorswitched off" to "motor switched on"status via switching or dimmingcommands or after a device reset, theactuator first always sets the cutting-inspeed. The cutting-in speed shouldensure that the motor starts up optimally(e.g. reliable start-up of the fan motorthrough transfer of a higher torque, andthus a higher fan speed). The cutting-inspeed is unalterably predefined as 100%.

Page 131 of 157



Dwell time in cutting-inspeedSeconds (0...59)

0...2...59 The parameter is only visible in the"speed controller" operating mode forthe "1-gang" device variant.The dwell time that can be configuredhere determines how long the actuatorallows the cutting-in speed to be active.The actuator changes to the predefinedrequired speed only after the dwell timefor the cutting-in speed has elapsed.This change always occurs rapidlywithout a dimming procedure. If therequired speed already corresponds tothe cutting-in speed (100 %), there is nochange.If the motor should be switched off whilethe cutting-in speed is set, the actuatorinterrupts the dwell time and switches offthe dimming channel immediately. Thisoccurs rapidly without a dimmingprocedure. As a result, soft OFFfunctions configured optionally in theETS will not be executed in this case.

5...9 Sets the dwell time milliseconds.

Behaviour after ETSprogramming

The actuator permits setting thebrightness value separately for eachdimming channel after programmingwith the ETS.

The dimming channel is set to thepredefined brightness value or speed(pay attention to configured minimumand maximum brightness!).The "basic brightness" setting is onlyavailable if the dimming range is limitedto the lower limit by the basic brightness.Furthermore, this setting is not availablein the "speed controller" operatingmode.

No reaction After programming with the ETS, thedimming channel shows no responseand remains in the switching brightnessvalue currently selected.

Behaviour in case ofbus voltage failure

The actuator permits setting thebrightness value separately for eachdimming channel in case of bus voltagefailure.

switch off The dimming channel is switched off. Itshould be noted that the configured OFFcommand can only be executed if themains voltage supply of the actuator

(terminal pair "L N") is switched on. Ifthe mains voltage is switched off, theactuator in this configuration shows noreaction (the last brightness stateremains active provided that the mainsvoltage on the dimming outputs is stillswitched on).

Basic brightness5 %10 %15 %...95 %100 %

The dimming channel is set to thepredefined brightness value or speed(pay attention to configured minimumand maximum brightness!). It should benoted that the brightness value or speedcan only be set if the mains voltagesupply of the actuator (terminal pair "LN") is switched on. If the mains voltageis switched off, the actuator in thisconfiguration shows no reaction (the lastbrightness state remains active providedthat the mains voltage on the dimmingoutputs is still switched on).The "basic brightness" setting is onlyavailable if the dimming range is limitedto the lower limit by the basic brightness.Furthermore, this setting is not availablein the "speed controller" operatingmode.

No reaction In case of bus voltage failure, thedimming channel shows no reaction andremains in the currently set brightnessvalue, provided that the mains voltageon the dimming outputs is still switchedon.

Behaviour after bus ormains voltagereturn

The actuator allows the brightness valueor speed to be set separately for eachdimming channel after bus voltagereturn. This parameter also defines thebehaviour after mains voltage return ifthere is no bus voltage on the actuatorat the time of mains return (on theterminal pair "L N"). If there is busvoltage at the time of mains return, theparameter will not be executed!

switch off The dimming channel is switched off.Basic brightness5 %10 %15 %...95 %100 %

The dimming channel is set to thepredefined brightness value or speed(pay attention to configured minimumand maximum brightness!).The "basic brightness" setting is onlyavailable if the dimming range is limitedto the lower limit by the basic brightness.Furthermore, this setting is not availablein the "speed controller" operatingmode.

and internally stored on bus voltagefailure will be tracked.

No reaction After bus or mains voltage return, thedimming channel shows no responseand remains in the state currentlyselected.

Activating staircasefunction

The staircase function is – irrespectiveof the 'Switching' object - activated afterbus or mains voltage return. With thissetting, make sure that the staircasefunction is also enabled. When thestaircase function is not enabled, thereis no reaction after bus/mains voltagereturn with this setting.In the "speed controller" operating modefor the "1-gang" device variant, thisparameter setting is called "activate timedimmer function".

Switch-on brightness Basic brightness5 %10 %15 %...95 %100 %

This parameter specifies the brightnessvalue, which should be set wheneverswitching on via the "switching" or"central switching" object or by manualoperation on the dimming channel. Theswitch-on brightness must always bebetween the upper and lower brightnesslimit value of the dimming range.The selection of "basic brightness" is notnecessary when using a minimumbrightness.This parameter is visible only in the"lighting control" operating mode.

Memory value(brightness beforeswitching off last time)

In the "Memory value" setting, the activeand internally saved brightness valueprior to switching off last time is setwhen switching on (via the "switching" or"central switching" object).

Dimming behaviourafter receipt of abrightness value

fading

A parameter is used here to definewhether a brightness value received viathe bus is instantly jumped to (absolutedimming), or whether the brightness isdimmed to via the set dimmingcharacteristic. Fading is also possible asan alternative. When fading, thereceived brightness value is reached inthe exact configured fading timeirrespective of the dimmingcharacteristic and irrespective of whichbrightness value the dimming procedurewas started at. Thus, for example,several dimming outputs can be set tothe same brightness at the same time.It is not possible to dim a speed valuevia "fading" in the "speed controller"operating mode for the "1-gang" device

version. Hence, this setting is notnecessary in the operating modementioned.

Time for brightnessvalue via fadingSeconds (0...59)

0...20…59 The fading time is set here if fading ispredefined in the dimming behaviour. Adimming procedure via fading lasts forthe exact configured time. If "0" is set,the brightness value is jumped todirectly.

Behaviour by relativedimming when OFF

This parameter defines whether or not adimming channel in the "OFF" statereacts to a relative dimming telegram.This parameter is only available in theapplication program with version "1.2"and only in conjunction with the devicegeneration "V02" in function.

Dimming up switcheschannel ON (Standard)

The dimming channel always reacts to arelative dimming telegram and executesa dimming process. In the "OFF" state,the channel switches on with a "dim up"telegram.

Dimming up is ignored(channel remains OFF)

The dimming channel only reacts to arelative dimming telegram when it isswitched on. In the "OFF" state, thechannel ignores a "dim up" telegram.

This parameter can be used to enablefeedback of the load type. Thecorresponding communication objectbecomes visible when enabled.

h Kx - FeedbacksFeedback switchingstatus ?

The current switching state of thedimming channel can be signalled backseparately to the bus.

no feedback No feedback object available for theswitching status. Switching statusfeedback deactivated.

Feedback object is activesignalling object

The "Switching feedback" object isenabled. The switching status istransmitted once the status is updated.An automatic telegram transmission ofthe feedback takes place after busvoltage return or after programming withthe ETS.

Feedback object is passivestatus object

The "Switching feedback" object isenabled. The switching status will betransmitted in response only if thefeedback object is read out from by thebus. No automatic telegramtransmission of the feedback takesplace after bus voltage return or afterprogramming with the ETS.

Updating the objectvalue for switchingstatus feedback

Here you can specify when the actuatorshould update the feedback value forthe switching status in case of anactively transmitting communicationobject. The object value updated by theactuator is then signalled actively to thebus.

after each update obj."Switching"/"Central"

The actuator updates the feedbackvalue in the object once a new telegramis received on the input objects"Switching" or "Central switching". Withan actively transmitting feedback object,a new telegram is also then activelytransmitted to the bus each time. Thetelegram value of the feedback does notnecessarily have to change in theprocess. Hence, a correspondingswitching status feedback is alsogenerated on the "Switching" objectsuch as in the case of cyclical telegramsfor example.

only if the feedback valuechanges

The actuator only updates the feedbackvalue in the object if the telegram value

Page 137 of 157



(e.g. "OFF" to "ON") also changes If thetelegram value of the feedback does notchange (e.g. in the case of cyclicaltelegrams to the "Switching" object withthe same telegram value), the feedbackthen remains unchanged. Consequently,with an actively transmitting feedbackobject, no telegram with the samecontent will be transmitted repeatedlyeither.This setting is recommendable, forinstance, if the "Switching" and"Switching feedback" objects are linkedto an identical group address. This isoften the case when activating bymeans of light scene push-buttonsensors (recall and storage function).This parameter is only visible in case ofan actively transmitting feedback.

Time delay for feedbacktelegram after busvoltagereturn ?

YesNo

The feedback telegram can betransmitted to the bus with a delay afterbus voltage return or after programmingwith the ETS. Setting "Yes" activates thedelay time of the feedback in case ofbus voltage return. The delay time isconfigured on the parameter page"General".This parameter is only visible in case ofan actively transmitting feedback.

Cyclical transmission ofthe feedback ?

The switching status feedback telegramcan also be transmitted cyclically via theactive message object in addition to thetransmission after updating.

Yes Cyclical transmission is activated.No Cyclical transmission is deactivated so

that the feedback telegram istransmitted to the bus only whenupdated by the actuator.This parameter is only visible in case ofan actively transmitting feedback.

Feedback brightnessvalue / speed ?

The current brightness or speed value ofthe dimming channel can be signalledback separately to the bus.

no feedback No feedback object is available for thebrightness value or speed. Brightnessvalue / speed feedback deactivated.

Feedback object is passivestatus object

The "brightness value feedback" objector "feedback of speed" is enabled. Thevalue will be transmitted in responseonly if the feedback object is read outfrom by the bus. No automatic telegramtransmission of the feedback takesplace after bus voltage return or afterprogramming with the ETS.

Updating the objectvalue for brightnessvalue / speed feedback

You can specify here when the actuatorshould update the feedback value forthe brightness value or speed in case ofan actively transmitting communicationobject. The object value updated by theactuator is then signalled actively to thebus.

after each update obj."brightness value" / obj."speed"

The actuator updates the feedbackvalue in the object once a new telegramis received on the input "brightnessvalue / speed" object. With an activelytransmitting feedback object, a newtelegram is also then activelytransmitted to the bus each time. Thetelegram value of the feedback does notnecessarily have to change in theprocess. Hence, a correspondingbrightness value feedback is alsogenerated on the "brightness value /speed" object such as in the case ofcyclical telegrams for example.

only if the feedback valuechanges

The actuator only updates the feedbackvalue in the object if the telegram value(e.g. "0 %" to "100 %") also changes. Ifthe telegram value of the feedback doesnot change (e.g. in the case of cyclicaltelegrams to the "brightness value /speed" object with the same telegramvalue), the feedback then remainsunchanged. Consequently, with anactively transmitting feedback object, notelegram with the same content will betransmitted repeatedly either.This setting is recommendable, forinstance, if the "brightness value /speed" and "brightness value feedback /speed feedback" objects are linked to anidentical group address. This is often thecase when activating by means of lightscene push-button sensors (recall andstorage function).This parameter is only visible in case ofan actively transmitting feedback.

Time delay for feedbacktelegram after busvoltagereturn ?

YesNo

The feedback telegram can betransmitted to the bus with a delay afterbus voltage return or after programmingwith the ETS. Setting "Yes" activates thedelay time of the feedback in case ofbus voltage return. The delay time isconfigured on the parameter page"General".This parameter is only visible in case ofan actively transmitting feedback.

Cyclical transmission ofthe feedback ?

The brightness value/speed feedbacktelegram can also be transmittedcyclically via the active message objectin addition to the transmission afterupdating.This parameter is only visible in case ofan actively transmitting feedback.

Yes Cyclical transmission is activated.No Cyclical transmission is deactivated so

that the feedback telegram istransmitted to the bus only whenupdated by the actuator.

Supplementary functionfor staircase function /time dimmer function

The staircase function can be extendedby the two supplementary functions"time extension" and "time processes viabus", which should be usedalternatively. The time dimmer functionin the "speed controller" operating modecan optionally be supplemented by the"time processes via bus" only.This parameter enables the desiredsupplementary function and therebyactivates the necessary parameters orobjects.

no supplementaryfunction

No supplementary function is enabled.

Time extension The time extension is activated. Thisfunction permits retriggering anactivated staircase lighting time spann-times via the object "Staircase functionstart/stop.The "Time extension" supplementaryfunction is not necessary in the "speedcontroller" operating mode for the"1-gang" device variant.

Time preset via the bus The time preset via the bus is activated.With this supplementary function, theconfigured switch-on time can bemultiplied by a factor received via thebus, thus it can be adapted dynamically.

Maximum timeextension

1-fold time2-fold time3-fold time4-fold time5-fold time

In case of a time extension (retriggeringthe lighting time n-times via the object"Staircase function start/stop), theparameterized staircase lighting time willbe extended by the value programmedin this parameter."1-fold time" means that after the startedstaircase time has elapsed, it can beretriggered a maximum of one moretime. The time is therefore extended twofold. The other settings behave in asimilar manner.This parameter is visible only if thesupplementary function "time extension"is set.

Staircase functionactivatablevia"Staircase time /Time dimmer" object ?

Yes

No

A time preset via the bus can specifyhere whether the receipt of a new timefactor also starts the switch-on time(setting "Yes"). At the same time, theobject "Staircase function start/stop /"time dimmer start/stop" is hidden.If the setting is "No", the switch-on timecan be activated exclusively via theobject "Staircase function start/stop /"time dimmer start/stop".This parameter is visible only if thesupplementary function "Time preset viathe bus" is set.

Reaction at the end ofthe staircase time / timedimmer function

At the end of the switch-on time, theactuator for the dimming channelconcerned displays the configuredbehaviour here. The channel can be setto switch off immediately, alternatively toexecute the pre-warning function or todim to a reduced continuous lighting(application: long, dark hallways), or toactivate a continuous speed (e.g. basicventilation).

switch off At the end of the switch-on time, theactuator switches off the dimmingchannel concerned. If the soft OFFfunction is configured, switching offtakes place via a dimming procedure.

activate pre-warning time At the end of the switch-on time, thedimming channel can generate a pre-warning (reduction of brightness /speed) prior to switching off. The pre-warning, for example, should warn anyperson still on the staircase that the lightwill soon be switched off.

activate reducedcontinuous lighting /activate reducedcontinuous speed (basicventilation)

At the end of the switch-on time, theactuator activates the reducedcontinuous lighting / continuous speedfor the dimming channel concerned. Thereduction of the lighting to continuouslighting is appropriate, for example, if acertain degree of artificial light should beswitched on permanently in long, darkhallways. Switching to switch-onbrightness by activating the staircasefunction normally takes place byadditional presence detectors or motiondetectors when people are present inthe hallway.The continuous lighting / continuousspeed remains permanently active afterthe switch-on time has elapsed. Onlywhen an ON telegram is received againvia the object "Staircase functionstart/stop" / "Time dimmer start / stop"does the actuator switch back to the

h Kx - Switch-on/switch-off behaviourSoft ON function ? Yes

NoThe soft ON function permits thedimming channel to be switched onmore slowly. If this function (setting"Yes") is activated, a dimming procedureto the switch-on brightness is executedafter receiving a switch-on telegram viathe "switching" or "central switching"object.No soft ON function is possible for the"1-gang" device variant in the "speedcontroller" operating mode.

Behaviour whenrecalling a scene

Jumping to brightnessvalue / speed

Dimming to brightnessvalue / speed viadimming increment time

When recalling a scene, the configuredor stored scene value is set for thedimming channel concerned. Thisparameter setting can define whetherthe brightness value or speed can beinstantly jumped to or dimmed to or isset via fading. When fading, the

Dimming brightness valuevia fading

brightness value to be set is reached inthe exact configured fading timeirrespective of the dimmingcharacteristic of a channel andirrespective of which brightness valuethe dimming procedure was started at.Thus, for example, several dimmingchannels can be set to the samebrightness at the same time. It is notpossible to dim a speed value via"fading" in the "speed controller"operating mode for the "1-gang" deviceversion. Hence, this setting is notnecessary in the operating modementioned.

Dimming increment time(0...255 ms)

0…5…255 Setting of the dimming increment time ifthe brightness value / speed value of ascene should be dimmed.This parameter is visible only if theparameter "behaviour when recalling ascene" is set to "dim to brightness value/ speed via dimming increment time".

Overwrite values storedin the device duringETS download ?

Yes

No

During storage of a scene, the scenevalues (current states of the dimmingchannels concerned) are storedinternally in the device. To prevent thestored values from being replacedduring an ETS programming operationby the originally programmed scenevalues, the actuator can inhibitoverwriting of the scene values (setting:"No"). As an alternative, the originalvalues can be reloaded into the deviceduring each ETS programmingoperation (setting: "Yes").

No

Setting "yes" enables the storagefunction of the scene. If the function isenabled, the current brightness valuecan be stored internally via theextension object on receipt of a storagetelegram. If "no" is selected, the storagetelegrams are rejected.

h Kx - Operating hours counterOperating hours counter?

no

yes

The operating hours counter can beenabled here. If the operating hourscounter is not enabled in theconfiguration of a DALI group or a singledevice, no operating hours will becounted for the DALI group or singledevice concerned. Once the operatinghours counter is enabled, however, theoperating hours will be determined andadded up by the ETS immediately aftercommissioning the DALI Gateway.If the operating hours counter issubsequently disabled again in theparameters and the Gateway isprogrammed with this disabling function,all operating hours previously countedfor the DALI group or the single deviceconcerned will be deleted. Whenenabled again, the counter status of theoperating hours counter is always on"0".
